Double Cylinder Door Knobs:

Double Cylinder door knobs, now we have all heard of double cylinder deadbolts, but what is a double cylinder door knob? A double cylinder door knob is a door knob that is keyed on both sides of the door, or in a place where the door that needs the option of locking on either side of the door. These door knobs are not very common at all that’s for sure. I was surprised to find that there is a need for them at times. I remember being asked two or three times if we had such a thing and at the time I didn’t know of anything like it, well except the Asylum lever locks. But with the Asylum levers it may limit the options of use a little because the levers on either side are inoperable (they generally use these on adjoining hotel suites and things like that). But we have found that the double cylinder door knobs do indeed exist. They are in the commercial door hardware section, because you most likely won’t find these on residential homes.

The double cylinder door knob we have on the site now is from EZSet, the EA Grade. It’s made for all the commercial kind of buildings like for an office, school, hospital, apartment, hotel, motel and all those other public buildings that get a lot of use. This lock is UL Listed and you can use it on any door that needs to be able to lock from both sides of the door. It’s not forced to lock like the Asylum function, but maybe that’s what you are looking for – an option to lock.

There are more door knobs with the double cylinder option from other brands that are not yet on the site like from Schlage and a few others may be able to make one up, so please contact us if that’s what you are looking for!


LockState Resort Locks:

The LockState Resort Locks are mainly for a land and/or building, unit, or room that you have available for rent. These locks help give you control and you won’t have to issue keys or codes that are permanent, and you don’t have to worry about monthly fees – the LockState Resort locks are at an affordable cost!

The LockState Resort Locks allow you as a property owner to provide your guests, contractors, cleaners, ect. with temporary access codes. These codes can start and end whenever you feel it’s necessary. You set the time for the lock to auto lock or auto unlock daily or you can set it for a one time use.  Resort Locks include daylight savings mode to adjust for daylight savings time and a lockout functionality. Plus the codes are unlimited over a year.

You will find that there are a few styles/designs in the Lockstate Resort Lock Section.  There are some heavy duty resort locks such as the RL4000, mortise (RL2000M), or maybe more basic like the RL2000. All of these have similar features, but some may include a few more features and are just have a little more heavy duty construction than the other. If you have a front door that is exposed to all weather conditions you will want to go with the RL4000. The RL2000M is a mortise, which may or may not work for you – it also has some weather resistance, but if you are going for full weather resistance, you will want the RL4000 – it’s the heaviest duty resort lock we carry on the site. LockState Resort Locks include other features such as, a lighted keypad for when your guests are entering or exiting at night, the more heavy duty locks are totally weather resistant, and these are available in Silver or Brass finishes.

Dummy Knobs:

Dummy door knobs and levers are often confused with the other function called passage. It’s mostly when someone is looking for a passage door knob which is a door knob or lever with no lock but it has a mechanism and it does function, and they mistakenly order a double or single dummy. Dummy door knobs and levers are non functioning and are mounted straight to the door. Most of these can not have a bore hole in the door or it will not work (the Sure-Loc Juneau Dummy lever set at one time did require a bore hole and it basically installed just like a regular passage but it didn’t have the mechanism to hold the door in place. I don’t know for sure, but maybe you can still find dummy sets still out there like that). So let me start again, most likely when you order a dummy or a dummy set (double dummy) they are mounted to the door, which means you most likely can’t have a hole or you won’t have any way of screwing the door knob onto the door.

What types of dummies are there?

Single Dummy:

A single dummy is one single non functioning door knob or lever that is mounted to the front of the door. Remember these will not mount to door that have a bore hole.

Double Dummy:

A double dummy set comes with two non functioning door knobs/levers. These are great to purchase if you have double closet doors (which are very popular) where all you do is pull them open. You can mount each door knob on the front of each door. Or you can mount these back to back if you want door knobs on both sides of a door, the Sure-Loc door knobs and levers require a spindle for it to be possible to mount them back to back, available upon request.

privacy locks

What are privacy locks?

A privacy function is used to secure the interior rooms of a home or you can see them on any kind of building really. Each is locked by either a thumb turn or a pushbutton on the inside of the door. The exterior will have a hole to insert an emergency key or I like to use a bobby pin. Usually the emergency key comes included to unlock from the outside of the door. These privacy styles are most commonly found on bathroom doors and bedroom doors.

What styles and types of privacy locks are out there?

There are so many styles, that’s for sure. I am sure the styles are endless. And by styles I mean the design and finish – the look of it. You can find the privacy function for your home in either a door knob or a door lever handle. You can even find some cool privacy bolts that are used pretty much like a regular deadbolt but it doesn’t require a key to unlock from the outside – you can use a penny!

Linnea Privacy Square Bolt Shown with the Emtek Hermes Lever – Passage Function,

This Linnea privacy bolt works well with a passage knob or lever. I think it looks so sleek.

There is also commercial privacy levers for commercial applications such as public building bathrooms like gas stations and office buildings or Hospital and grade school privacy functions that are unlocked from the outside by turning an emergency turn button and a push button to lock from the inside. Other great privacy locks for commercial applications are the faculty restroom locks where the interior push button inside activates a visual occupancy indicator that allows only an emergency master key to operate. Also check out the Schlage Commercial Restroom Indicator Deadbolt for public bathrooms, which includes a green vacant sign when unoccupied and red in use sign when the door has been locked.

Commercial vs Residential Door Hardware

The difference between Commercial and Residential door hardware comes down to grade or quality and better grade means you can pretty much use it more without it breaking on you. You would probably never put a residential door knob (or any other type of hardware for that matter) on a commercial application like a public office building like a dentist’s office for example, a residential door knob wouldn’t last a month – this goes for any type of door hardware, like hinges and any other misc. hardware for doors too. Commercial doors are going to get a lot of use, whether its the bathroom or the front door. And for Residential applications like your home, you don’t need commercial grade hardware for your home a simple 3 grade door knob or residential hinges should do the trick. Unless you have a large family like a customer who called in did and the door knob would keep breaking within a few months and they had to replace it two to three times, in that case maybe you do need a commercial grade door knob.


Commercial hardware generally has an ASI grade of 1 or 2, one being the highest and most heavy duty. Commercial hardware not only have heavy duty grades, but also lots of commercial buildings require the hardware to meet certain specifications such as UL Listing, ADA Compliant. You can find all different types of commercial hardware to fit the application you have, check here.


Residential hardware is used for your home. You don’t have a ton of people opening and shutting your door a hundred times a day – well maybe you do (like the man I mentioned earlier) I don’t really know, but nine times out of ten I am sure most homes don’t. Residential hardware is made for doors that don’t get as much wear and tear – if you are using a residential door knob for example on a commercial application and it breaks more than once (which it most likely will) and even though some manufactures have warranties that cover for years or even a lifetime – the warranty may be voided if the hardware is being used on a commercial application rather than residential. So make sure you are using your residential hardware on residential applications if you want your warranty to cover replacements.



interconnect locks

Interconnect (also known as emergency egress) locks are offered all over the site. Interconnect lock’s interior mechanism, like shown above, makes it possible when turning the knob/lever below will release the lock on the deadbolt above and making it a quick and easy exit. This interconnect device option is only available with the single cylinder, not the double cylinder, as the double cylinder requires a key to unlock from both sides. If you are looking in the handleset section,  you want to look for the handlesets that have a full back plate and you can see that the deadbolt and handle are sharing the plate (see image below), all of the Emtek handlesets with the full back plate have an interconnect device option and you will just have to mark the box if you want the feature. There are also Baldwin handlesets with this interconnect feature.

A handleset that has a separate deadbolt from the handle, like shown above on the right, can not include this feature.To make it easier to search for interconnect handlesets, click on the Emergency Egress/Interconnect button under the handle sets category at the top. It will give list all of the handlesets with the interconnect mechanism.

You can also find the interconnect feature with some of the sideplates. All of the Emtek 5 1/2″ CC Sideplates have the interconnect device option if you are ordering the single cylinder (not double cylinder) if you choose to select it when ordering. Interconnect devices are not available for the Emtek 3 5/8″ CC sideplates.

Looking for commercial grade for with this feature? Under commercial hardware there is a list of categories to the left and you can “narrow by style” by clicking interconnected locks. You can scroll down through all the interconnected locks and find what will work for your application! Now when looking through the commercial interconnect devices after looking for a full plate under the handleset category, you might think that some of these aren’t right because the deadbolt is separated from the lever. It looks that way on the exterior part of the lockset, but all of the commercial interconnect locks have a full plate on the inside of the door and the mechanism works the same.

The interconnect locks or emergency egress locks make exiting so much more simple all you need is one hand. It’s a good feature to have for commercial applications especially in case of an emergency.

All About Sideplates

We did already introduce the side plates on this blog before, but it wasn’t in great detail like I am about to do here in this post. They are super classy and some are super fancy. They kind of remind me of the antique hardware that you find on really old doors, you know with the skeleton keys?

A side plate is basically a large back plate with a knob/lever and added deadbolt for an exterior door or it can be a blank plate with just the knob/lever as a privacy or a passage function for the interior doors. Side plates come in all kinds of designs and each side plate comes with a huge selection of interior knob or lever handles to choose from. So that means the options are pretty much endless.

I forgot to mention these are Emtek side plates. Anyway, Emtek side plates are offered with 3 5/8″ CC or a 5 1/2″ CC (CC – meaning center to center measurement from bore hole to bore hole). 5 1/2″ CC is more the standard prep for a door (read more about standard prep here). We have it divided down the middle, one side being 3 5/8″ CC Sideplates and one side beind 5 1/2″ CC sideplates, (see circled in yellow below).

So you have your pick between 2 different kinds of door preps, but then you also have a choice between keyed or non keyed side plates. Keyed being a side plate with a deadbolt, and there is a dummy keyed function as an option too. Non keyed is a big plate with no deadbolt with an option of privacy, passage or dummy functions.

There really is almost no end to the choices of mixing and matching all the door knobs and levers and back plate styles and then there are the finish options! These Emtek side plates can go anywhere in the home with anything!

Standard Door Prep

What is standard for door prepping? We talked all about door thickness in this post, so then what is the standard door prep? The door prep is basically talking about the part where the door hardware goes, you know the holes in the door where you will eventually install the door knob, lever, handleset and/or deadbolt.  I am reminding you now that I am talking about standard door prep, that doesn’t mean your door can’t be prepped differently. Standard prep is the easiest to find replacements for and standard prep is how the door will come if you were to buy a door at home depot or something like that. Starting with an Entrance door,

Exterior/Front Door Prep

Entrance doors usually have two bore holes. Because it requires a deadbolt above and that goes for if you order a handleset, sideplate or just a basic deadbolt with entrance knob/lever. And the standard bore hole size is 2-1/8 inches in diameter and the cross bore hole is 1 inch diameter. If you measure the standard distance from bore hole to bore hole or the center to center (CC) measurement, it is 5-1/2 inches (there are some other commonly used size CC preps like 3-5/8″, 2 7/8″ or even 6″ CC – so don’t think you are at a loss if your door is not standard – call us). You can see where the backset’s measurement is shown at the bottom of the image – standard backset is 2-3/8 inches or 2-3/4 inches.


This other standard door prep is for basically any other door that does not require a deadbolt lock like a passage, privacy or and keyed entrance function. You will see most of these type of preps on interior doors. It’s pretty much the same as the first, 2-1/8 inch diameter bore, 1″ cross bore and 2-3/8 inches or 2-3/4 inches backset.

If you have standard prep, you can pretty much order any type of hardware you want as most everything easily accommodates the standard prepping, but don’t fret if you don’t have standard doors, we have hardware for that too! All you have to do is measure then contact us and we can help find what will work on your door whether it’s standard or not!


Ball, Steeple and Finial Tips for Hinges:

Ball tips, Steeple Tips and Finial Tips are fabulous little decorative tips to dress up a door hinge. There are some hinges you will find that come with the tips already included on the hinge. For instance, Omnia and Taamba have a few different styles or you can check out Nostalgic Warehouse’s in the Antique Hardware section. These hinges from Taamba and Nostalgic Warehouse are more on the dressier side of hinges. Check out this decorative hinge from Taamba,

The ball tips and steeple tips from Emtek are ordered separately from the hinges. Ball and steeple tips, not to be confused with the Extended Button Tips, which are threaded, extended tips that attaches to the solid brass hinges so that the Emtek Hinge Pivot Stop can be used on the Emtek Solid Brass hinge. All Emtek Hinge tip sets are included with four tips and threaded pins for one pair of hinges. And each tip set is different to fit each size set of hinge that Emtek offers, so when ordering make sure it will fit the same size hinge you are ordering or already have. They are compatible with the Solid Brass Residential Duty hinges, Heavy Duty hinges and Ball Bearing hinges. And you can get the tips in Polished Brass, French Antique, Oil Rubbed Bronze, Satin Nickel, Pewter, Polished Chrome, Satin Chrome, Flat Black, Deep Burgundy, Medium Bronze, Rust, Silver, Patina and Satin Steel!

Omnia Door Hinge Finials are just like the steeple tips and ball tips, except there are a few more tip styles to choose from and will fit on any Omnia brand hinge (a little more simple to order than Emtek).

The Acorn, Ball, Crown, Steeple, and Urn Finials will fit any size Omnia hinge or either plain or ball bearing. These are threaded and will simply screw on to the ends of the hinge and you do not need to remove the hinge pin to attach.

ADA Compliant:

ADA stands for The Americans with Disabilities Act, or a law that was put into practice by the United States Congress in 1990. President George H. W. Bush signed this act into law on July 26, 1990. It’s been a law for a little over two decades, although minor changes were made later and effective January 1, 2009. Basically The Americans with Disabilities Act provide guidelines for a product (in our case, doors and door hardware) to meet requirements and rules to make it safe and easy for people with disabilities. Not all door hardware is ADA compliant; although some hardware may fit every rule they may not have the stamp of ADA approval. Generally ADA compliant hardware is in the commercial hardware section, but there are more residential style brands that meet these requirements like some of Weslock’s Levers for example – you will see the ADA symbol marked on the pages of the hardware.

More and more building codes are specifically asking for ADA (American Disabilities Act) compliant products. New laws are being incorporated into building codes to allow people with disabilities, such as people using wheel chairs, scooters, walkers or any other sort of disability that limits mobility, more access as well as travel buildings in a much safer way.

Door hardware such as door closers need to meet ADA requirements of strength and size. To be ADA compliant, an interior door can not open with an opening force of more than 5 pounds. Door Hardware handles, pulls, latches, locks and other operating devices on accessible doors should have a simple shape that is easy to grip with one single hand and it should not require tight grasping twisting of the wrist to operate. Levers must have a push type mechanism, U-shaped handles designs are acceptable. For sliding doors – when the sliding doors are opened fully, the hardware must be exposed and usable from both sides of the sliding door. Hardware for accessible doorways should be mounted no higher than 48 inches from the floor. Entrance doors should be connected by an accessible route to all spaces or elements within the building, and to accessible parking and passenger loading zones, public streets or sidewalks if available.
