Right-Hand Mortise Lever Entry Lock
This Marks USA 2750B/3 mortise lever lockset is finished in polished brass and configured for right-hand doors. It operates as a single-cylinder entry set with a keyed exterior and a thumb-turn interior, supplied keyed different for individual access control.
1-Inch Backset and 8-1/4-Inch Mounting Spacing
The lock requires a 1-inch backset preparation and mounting screw holes spaced at 8-1/4 inches, limiting installation to doors and frames cut to those exact dimensions. The lock face plate measures 1 inch by 9-7/16 inches, so the mortise pocket must match this footprint.
Thinline Slim Line Series for Storm Doors
Designed as a Thinline Slim Line lockset, this model suits narrow-stile storm doors where standard mortise bodies will not fit. Buyers needing a wider backset, left-hand handing, or a double-cylinder function must select a different lock.

Questions about this item
Does the 2750B/3 come in other finishes or handing options?
The supplier lists this model only in polished brass with a right-hand configuration; no alternative finishes or left-hand versions appear in the data.
How does the 1-inch backset affect installation on a standard storm door?
A 1-inch backset positions the cylinder closer to the edge than typical residential locks, so the door stile must be at least that deep and the 8-1/4-inch screw-hole spacing must match existing prep.
What does the single-cylinder function mean for daily use?
The lock is operated by a key on the exterior and a thumb turn on the interior, allowing free egress from inside while securing the outside with a key.
