85mm Narrow Mortise Lock
The DIROCK 85mm center distance narrow mortise lock developed for aluminum and narrow stile door profiles. It combines a latch bolt with a deadbolt in a compact, slim body, with 30mm and 35mm backset options. Manufactured to EN 12209, the 85Z narrow lock accepts standard euro profile cylinders and lever handles. It is ideal for commercial projects with strict lock body size requirements and retrofitting applications.
