These mortise lock assemblies are constructed of steel and diecast components and come in a brass plated finish. This mortise case lock is designed for indoor use only, and it functions with the use of a spring-loaded square drive spindle at maximum width and height of 1/4 in.. It ships handed (to close in a certain direction), but the latch can be reversed for opposite swinging doors. This mortise lock assembly is used with antique and vintage door hardware and it features a 2-3/8 in. backset. The latch includes a latch and deadbolt strike with fasteners, but it does not include any of the following components and they must be purchased separately: the doorknobs, square spindle, spare keys, and trim plates. Note #1: the square drive on this latch has a 9/32 in. opening, but it will only accommodate 1/4 in. square spindles. Note #2: This item cannot be used on pre-bored doors that have large, newer style doorknob 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 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® is purchased separately. Installation tip #3: see the manufacturer’s how-to video which shows how to reverse the handing of the door latch.
