Prime-Line Vintage Style Indoor Mortise Lock Assembly Kit, Backset, 1/4 in. Max Square Spindle, Rev. Latch Blt, 1 pk.

When it's time to replace damaged or missing vintage-style mortise door locks, look no further than Prime-Line's Mortise Lock Assembly Kit. The cast steel construction and brass plated finish closely match the mortises of period homes and are perfect for antique doors. The skeleton key locking system and vintage look of the faceplate won't take away from the originality of the antique hardware throughout the home. The mortise lock assembly set has a 2-3/8 inch backset with a 9/32 inch square spindle drive that accepts a maximum spindle size of 1/4 inch. The kit includes a latch and deadbolt strike with fasteners (door knobs, square spindle, and trim plates sold separately) and two skeleton-style keys. Although the lock set ships handed (to close in a certain direction), the latch can easily be reversed for opposite swinging doors. Installation of the bronze steel mortise lock set is quick and easy, and all mounting screws are included. The mortise lock easily slides into the existing door pocket for an economical replacement of damaged or missing vintage lock sets that will perfectly complement the antique design of your home. Installation Tip: This item cannot be used on pre-bored doors that have large, newer style door knob holes without first prepping them to receive this hardware. Installation Tip: Because the fasteners of the rosettes (purchased separately) require a solid surface to mount to, the large 2-1/8 inch (approximate size) holes must first be filled with a hardening filler, to then be able to receive the rosette fasteners. Products like Fix-It-All and Bondo Body Filler have worked well for some, but care must be used to avoid damaging any prefinished door surfaces during application and finishing. Installation Tip: Apply a small amount of Loctite ThreadLocker 271 to the set screw threads in the event they are loosening - Loctite must be purchased separately. "
