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: 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.
