These passage door latches are constructed of steel and come in a brass plated finish. This latch is designed for indoor use only, and it functions with the use of a spring-loaded square drive spindle at a maximum width and height of 9/32 inches. It is used with antique and vintage door hardware and it features a 2-3/8 in. backset. The latch includes a latch strike and fasteners, but it does NOT include any of the following components and they must be purchased separately: The door knobs, square spindle and rosettes. *Note #1: The square drive on this latch has a 9/32 in. opening and a 1/4 in. opening. The maximum square spindle size that this latch will accommodate is 9/32 in. Note #2: 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 #1: Because the fasteners of the rosettes (purchased separately) require a solid surface to mount to, the large 2-1/8 in. (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 #2: Apply a small amount of Loctite ThreadLocker 271? to the set screw threads in the event they are loosening ? Loctite? purchased separately. Used with interior mortise locks with square spindle Dimensions are 1 in. x 2-1/4 in. Comes in a classic bronze finish Constructed of durable steel All necessary mounting hardware is included for a quick and easy installation For further dimensional information, please see the line drawing
