Single Cylinder Vs. Single Sided


This can be a little confusing if you had no clue there was a difference, but in fact… there is a difference. And once you know what the difference is, I’m sure you will laugh.

Or not…

Lets get down to the nitty gritty…

Get it?

Single Cylinder has that thumb turn thingy on the inside, while the Single Sided has nothin’, noda zip.

NOTE: The bore hole for the “single sided” deadbolt is drilled only partially through the door so from the outside you don’t see the deadbolt. If your door already has a bore hole completely through the door, this type of deadbolt will not work for you.
