REPLACE ANTIQUE MORTISE LOCK SETS – The vintage look of the Prime-Line E 2294 Mortise Lock Assembly Kit is a great match for the old lock sets found in period homes. Used with antique and vintage door hardware, the kit is an economical replacement for indoor mortise locks. EASY INSTALLATION – Installation is quick and easy, and all mounting screws are included. The mortise lock easily slides into the existing door pocket for an fix for a broken lock. It has a 2-3/8” backset with a 9/32” square spindle drive that accepts a maximum spindle size of 1/4”. STEEL WITH BRASS-PLATED FINISH – The E 2294 lock is constructed from case-hardened steel and features a faceplate with a bright, brass-plated finish. The kit includes a latch and deadbolt strike with fasteners (door knobs, square spindle, spare keys and trim plates sold separately) and two skeleton-style keys. LEFT OR RIGHT-HANDED INTERIOR DOORS – The mortise caselock ships handed (to close in a certain direction) but the latch can easily be reversed for opposite swinging doors. INSTALLATION TIP – Although the square drive on the latch has a 9/32” opening, it will only accommodate 1/4” square spindles.
