Interior MortiseA mortise lock is a lock that requires a pocket – the mortise – to be cut into the door. The lock is installed into the pocket in the edge of the door. If your door is not already prepared for a mortise lock, you (or a skilled professional) will have to use a mortise saw to cut into the door so the lock fits properly. Our mortise locks fit 2-1/4 inches Backset and include a skeleton key locking mechanism. |

How to Measure for Backset?
When installing a tubular latch with passage or privacy function, it’s very important that you know what your backset measurement is – either 2-3/8 or 2-3/4 inches. (see graphic).
The backset is the distance from the edge of the door to center of the 2-1/8 inches (54 millimeter) diameter bore hole.
In the U.S., there are two common backsets for residential door locks, 2-3/8 or 2-3/4 inches.
Dummy sets have no latch and are surface mounted, therefore a backset measurement is not needed.
Nostalgic Warehouse Interior Mortise locks are only offered in 2-1/4 inches backset. Our mortise locks are recommended for interior use only.
Jessica –
We bought other crystal style door knobs that were a different brand bc they were cheaper but they ended up hurting our hands so we ordered these. We have ordered several different kinds from this company now and have been impressed every single time.
