Master Lock Company MLKSLCHSR26D Storeroom Door Lock

Product Description

The MASTER LOCK COMPANY MLKSLCHSR26D is a heavy-duty cylindrical storeroom door lock built for locked storage room applications. The outside lever remains locked at all times while the inside lever stays unlocked, meeting the functional requirements of a true storeroom function lock. It features a BumpStop advanced cylinder that resists bump attack methods, a six-pin Schlage C compatible keyway, and a satin chrome finish. The unit ships with an ASA strike and a UL-listed latch. It meets ANSI/BHMA A156.2 Grade 2 commercial door hardware standards. Licensed locksmiths, commercial door hardware installers, and facilities maintenance professionals are the typical installers.

This lock is suited for storage rooms, supply closets, and utility spaces in commercial and light-industrial buildings where controlled outside access is required but unrestricted egress from inside is necessary. The cylindrical construction fits standard residential and light-commercial door prep. The 3-1/4 inch trim diameter and 2-3/4 inch backset dimension make it compatible with common door prep layouts found in commercial renovation and new construction work.
