Satin Chrome Right-Hand Mortise Lever Lock

The Marks USA 2750B/26D is a Thinline Slim Line mortise lever lockset finished in satin chrome. It is designed for right-hand doors and uses a single-cylinder mechanism with an exterior keyway and an interior thumb turn. The brass construction and 1-inch backset suit commercial storm-door applications where a narrow-profile lock body is required. The lever trim is thru-bolted and uses spring-loaded, self-adjusting spindles with screwless levers.

Replaces Wide-Body Mortise Locks on Narrow Stiles

This lockset replaces bulkier mortise hardware when the door stile cannot accommodate a standard case width. The upgrade is worth it when mounting screw holes must match an 8-1/4-inch spacing and a 1-inch backset is specified. It also replaces two-piece assemblies by integrating the deadbolt and latch into a single Thinline case. Buyers who need a left-hand configuration or a double-cylinder function cannot use this specific model.

Fits Storm Doors with 1-Inch Backset Prep

The lock fits storm doors prepared for a 1-inch backset and an 8-1/4-inch screw-hole pattern. The 1-inch by 9-7/16-inch face plate covers standard mortise cutouts without additional routing. Thru-bolted trim assemblies secure the lever plates directly through the door, freeing the installer from surface-mounted screws that can loosen over time. The screwless lever design removes the need for set-screw adjustments during installation.
