Right-Hand Mortise Entry Lock

This Marks USA 2750C/26D is a right-hand mortise lever entry lockset finished in satin chrome. It belongs to the Thinline Slim Line series and is built from brass for commercial-grade durability. The double-cylinder function requires a key on both the interior and exterior sides. It suits steel security doors and storm doors in commercial settings.

1-Inch Backset and Double-Cylinder Security

The lock operates with a 1-inch backset and a 1-inch deadbolt throw, fitting doors prepared to that specification. Keyed-different cylinders provide unique access control per unit. The double-cylinder design secures both faces of the door, preventing entry even if adjacent glass is broken. Buyers needing a single-cylinder or thumb-turn interior release should select a different function.

Thru-Bolted Trim with 8-1/4-Inch Screw Spacing

The lever plate trim assemblies are thru-bolted for rigid mounting and use spring-loaded, self-adjusting spindles with screwless levers. Mounting holes are spaced at 8-1/4 inches centre-to-centre, so the door must match that pattern. The right-hand orientation determines the lever swing direction and cannot be reversed on site. Installers should verify door handing and hole spacing before ordering.

Questions about this item

Will the 1 inch backset match the existing mortise pocket on my older steel security door?

The lockset is built with a 1 inch backset and a 1 inch by 9-7/16 inch face plate, dimensions common on many steel security and storm doors; verify your current pocket matches these measurements before installing.

How can I confirm the double cylinder operates correctly once fitted?

After installation, insert the key on both the interior and exterior sides; the deadbolt should extend and retract smoothly from either cylinder without binding, confirming the double cylinder function is working.

Does the box include the cylinders and keys, or must they be ordered separately?

The lockset ships as a complete double cylinder assembly with both cylinders and corresponding keys included in the box; no separate cylinder purchase is required.
