Installers needing a mortise strike for 5/8" throw

This strike works with locksets having up to a 5/8" throw based on a 1/8" door gap. The mortise cavity requires a depth of 9/16", width of 9/16", and height of 1-1/2" with a 1-5/8" backset. Buyers needing a different cavity size or a higher voltage range should look at other models. It is not suited for cylindrical lock prep or surface mounting.

9/16" deep mortise cavity requirement

The single specification that decides fit is the 9/16" cavity depth combined with the 1-5/8" backset. The jamb must accommodate this exact mortise pocket for the strike to sit flush. Verify the existing door frame prep matches these dimensions before purchase. The 10 to 16 VAC operating range also requires a compatible transformer.
