A door hinge with a non removable pin isn’t uncommon, but that’s not to say that it is common. Yes we get customers from time to time requesting this specific type of hinge, but why? I’m sure you have figured out what a non removable pin hinge is. It’s hopefully pretty self explanatory. It’s where the pin of the hinge can not be removed when the door is shut.
So why would you want this, why would people request this? Because it may be a little harder to install the door, some of the hinges will require you to have to take the entire hinge off along with the door if for some reason you are removing the door. There are some brands that have a screw that holds the pin in place and when the door is completely shut you can not remove the pin, but you can remove the pin from the inside when the door is open by removing the screw. This makes it easier to install the door(s). Now back to the question why most people even order this option. Sometimes you will find an exterior door where the door opens out, or in other words the hinges are exposed on the outside of the door. If you order regular hinges, an intruder could easily tap out the pin and get inside. They wouldn’t even have to think about messing with the lock. So non removable pins come in handy for this purpose. It keeps the owner worry free.
