Right-Hand Dormitory Mortise Lock

This right-hand mortise lockset is built for dormitory and exit doors where panic-proof egress is required. The F-function design unlocks from the outside with a key and from the inside by simply rotating the knob, which retracts the bolt and shifts the rocker to prevent re-entry without a key. A satin chrome finish provides a clean, commercial appearance. It fits doors between 1-3/8 and 1-3/4 inches thick.

Installation Requirements and Door Prep

The lock requires a standard 2-1/2 inch backset mortise pocket and a 1 inch deadbolt bore in a door of compatible thickness. The 1 inch by 7-1/8 inch front face plate covers the mortise cavity. Because the unit is handed, the door must swing right-hand for the latch and thumb-turn orientation to operate correctly. No additional cylinders or trim are needed beyond what is supplied in the box.

Suited for Dormitory and Exit Applications

This lock suits facility managers securing student housing, assisted-living rooms, or any interior corridor door that must lock automatically after free egress. It is not intended for doors thinner than 1-3/8 inches or thicker than 1-3/4 inches, nor for left-hand door swings. Buyers needing a different handing, a larger backset, or an electronic access option should look at other models.

Questions about this item

How does the F-function dormitory operation handle repeated locking cycles during a full day of use?

The mortise mechanism unlocks from the outside with a key and from the inside by rotating the knob, which retracts the 1" deadbolt and shifts the internal rocker to prevent re-entry without a key.

What heat or noise does the lock produce when the bolt is thrown and retracted continuously?

The mechanical mortise action has no motor or electronics, so it generates no measurable heat and only the audible click of the bolt and rocker engaging.

Which door thickness and backset must the opening already have for this right-hand unit to install?

The lock fits doors 1-3/8" to 1-3/4" thick and requires a 2-1/2" backset with a 1" x 7-1/8" mortise pocket.
