Right-Hand Mortise Lockset

The Marks USA 22DW-3-RH is a polished brass mortise lockset designed for right-hand doors. It operates with a vestibule storeroom function where the outside knob remains locked at all times. A key retracts the latchbolt from the exterior while the interior side stays freely open. This latch-only unit includes no deadbolt or thumb turn.

Check Door Handing and Thickness

Verify that the door swings right-hand before ordering this non-reversible lockset. The lock fits doors ranging from 1-3/8 inch to 1-3/4 inch thick. Confirm the existing mortise pocket matches the 2-1/2 inch backset and the 1 inch by 7-1/8 inch front face plate dimensions. Ensure the application requires a latch-only function without a deadbolt.

Installation Requirements and Security Role

The lockset mounts into a standard mortise pocket in steel or wood doors and includes all necessary hardware. A mortise cylinder on the exterior accepts the two supplied keys for keyed-different access. The solid brass cylinder resists wear in commercial environments. This unit secures vestibule or storeroom doors by keeping the exterior locked while allowing free egress from inside.

Questions about this item

Does the lockset include the mortise cylinder, keys and mounting hardware, or must any of those be purchased separately?

The set ships with a solid brass mortise cylinder, two keys and all mounting hardware needed for installation; no additional parts are required.

Should I choose the right-hand or left-hand version for my door?

The lock body is reversible, so this single unit works on both right-hand and left-hand doors.

How does the vestibule storeroom function behave once the lock is fitted to a steel gate?

The outside knob stays locked at all times; a key retracts the latch to open the gate, and removing the key relocks it automatically, while the inside knob always turns freely.
