These passage door latches are constructed of steel and come in a chrome 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 in. 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 inches. 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. Can be used with any 2-3/8 in. backset handle that has a 9/32 in. or 1/4 in. square drive Chrome plated finished faceplate This door latch is ideal for use on an old style or antique interior square drive spindle lockset Chrome plated diecast Mounting hardware included Easy to install in less than 30 minutes with a few simple tools A Phillips head screwdriver is required for installation For further dimensional information, please see the line drawing
