Product Identity
The Marks USA 21AC/26D-W-RH is a satin chrome mortise lockset designed for out-swinging doors. Its right-hand reverse configuration and ornamental Unilock knob provide a secure, commercial-grade entry solution for steel gates and security storm doors.
Critical Specification
The double-cylinder function requires a key to operate the 1" deadbolt from both sides. This specification determines whether the lock meets egress requirements for your specific application and local building codes.
Installation Context
The lock fits doors between 1-3/8" and 1-3/4" thick with a 2-1/2" backset. Through-bolted knob plate assemblies anchor directly through the door. Two mortise cylinders and all mounting hardware are included, though the reversible design also accommodates left-hand doors if handing is changed during installation.

Questions about this item
How does the 2-1/2" backset affect where the lock sits on my door?
The 2-1/2" backset places the cylinder centre 2-1/2 inches from the door edge, so the mortise pocket must be cut at that distance for the lock body to align.
What does the double-cylinder function mean for daily use?
Both sides require a key to operate the deadbolt; the latchbolt retracts by knob inside, but locking or unlocking the bolt always needs a key.
What door thickness range does the mortise body accommodate?
The lock fits doors from 1-3/8" to 1-3/4" thick; the through-bolted trim assemblies clamp securely across that range.
