Marks USA 2750C/26D Thinline Ornamental Iron Lever, Double Cylinder with Plate, Entry, 1", AR1, Satin Chrome

The Marks USA 2750C/26D Thinline Series is an entry-function mortise lockset crafted for decorative iron doors requiring keyed access on both sides. With its ultra-narrow 1″ backset and 1″ deadbolt throw, this model fits slim-frame applications where standard mortise locks are too bulky.

Marks USA has been a primary manufacturer of ornamental-iron storm-door locks for many years. During that time, many innovative improvements were developed to increase reliability and ease of installation. These innovations include the Uni-Lock model with single-screw assembly, elimination of threaded swivel spindles in favor of the more secure thru-bolted design, helper springs in lever-rose sets, and steel hubs for greater endurance.
