Polished Brass Double Cylinder Mortise Lock

The Marks USA 22AC/3-W RHR is an ornamental mortise lockset finished in polished brass. It uses a double-cylinder mechanism with a 2-1/2" backset and a 1" x 7-1/8" face plate. Screwless knobs and self-adjusting spindles simplify installation on compatible doors. This right-hand reverse unit is sold keyed different.

Gates needing right-hand reverse ornamental entry

Suits iron gates or doors requiring a decorative double-cylinder mortise lock with a polished brass appearance and right-hand reverse handing. Not for doors with a different backset, left-hand or standard right-hand swing direction. Buyers needing a single-cylinder function or a non-ornamental design should look elsewhere.

2-1/2" backset dimension

The 2-1/2" backset is the critical measurement determining fit; it defines the distance from the door edge to the centre of the keyhole. Verify this exact dimension on your door before ordering. An incorrect backset prevents the lock from aligning with the door preparation.

Questions about this item

What does the 2-1/2" backset determine for this mortise lock?

The 2-1/2" backset sets the distance from the door edge to the centre of the keyhole, fixing where the mortise pocket must be cut.

What door thickness and handing does the right-hand-reverse iron-gate lock require?

The lock is built for right-hand-reverse doors — hinges on the left, lock on the right, door pulls toward you — and the thru-bolted trim fits standard gate thicknesses.

How are the screwless knobs and self-adjusting spindles installed on the 1" x 7-1/8" faceplate?

Insert the spindle through the mortise body, slide each knob on until the internal spring clip engages, then secure the faceplate with the thru-bolts — no visible screws on the knobs.
