Patio Door Locks
The Problem
National/Amerock patio door locksets were unique. The narrower style of Patio Door Units with vertical wood around the glass will not accommodate a normal backset of 2 3/8”. National Lock developed a 2” backset lock that would fit this application. Amerock later acquired National and continued producing the 2” backset.
In addition, the patio door passage was designed to be near the door (short projection from the door) allowing for a sliding screen door to be built into the frame of the patio door unit and the screen to slide by the lockset lever unit. If you are using a screen door, a full projection (standard) knob/lever set will interfere with the screen door.
The National/Amerock Patio door locks with a 2” backset are no longer manufactured. Replacement parts for this lock not readily available.
The Solution
Find another company that sells a good quality deadbolt, lever set and knob set.
