Commercial Storeroom Mortise Lock

This heavy-duty MAXTECH mortise lockset provides a right-hand storeroom function with a 2-3/4" backset. The latch-only design uses a scissor latch and anti-friction latch for reliable operation. Solid brass construction with a satin chrome finish suits commercial, institutional and residential doors. The vestibule function keeps the outside knob always locked while allowing free egress from inside.

Verify Door Handing And Prep

Confirm the door is prepped for a right-hand mortise lock with a 1-1/4" x 8" wide face plate cutout. The thru-bolted screwless knob plate assemblies require compatible through-door mounting holes. Ensure the existing cylinder cutout accepts a solid brass cylinder and that no interior thumb-turn is needed for this storeroom application. Check that the 2-3/4" backset matches your door preparation exactly.

Upgrade From Cylindrical Or Worn Mortise Locks

This lockset replaces lighter cylindrical locksets or worn mortise hardware where heavier security is required. The jump is worth it when a facility needs a vandal-resistant storeroom function with screwless trim that resists tampering. It also suits projects specifying a Marks New Yorker 7NY10DW/26D equivalent with solid brass components and a wide face plate for door reinforcement.
