Compatible Handleset Styles

This mortise lock body fits Marks handlesets including Cambridge, Crown, Grand Crown, Georgetown, Heritage, Madison, Grand Madison, Newport, Portland Disc, Towne, Grand Towne Disc, Claremont Disc, Wharton and Georgian. Discontinued handle styles marked Disc still work with the 8 Series body. The sectional mortise design suits commercial and heavy residential doors. Verify your existing trim matches the listed series before ordering.

Vestibule Function Without Thumb Turn

The vestibule function keeps the outside lever always locked while the inside lever remains free for egress. There is no interior thumb turn, so the lock cannot be unlocked from inside by hand. This suits storerooms or corridors where key-only entry is required. It is not for rooms needing a privacy turn or passage sets that unlock from either side.

Latch-Only Body With 2-1/2 Inch Backset

The lock body contains a latch bolt only with no deadbolt or rocker mechanism. A 2-1/2 inch backset and a 1-1/16 by 7-5/8 inch face plate are the critical dimensions for mortise pocket fit. Left-hand handing is fixed and cannot be reversed in the field. Buyers who need a deadbolt or reversible handing must select a different mortise lock body.

Questions about this item

Does the lock body ship with handles, cylinders or mounting hardware?

The Marks 8DW/3 is a body-only mortise lockset; handles, cylinders, trim and mounting hardware must be purchased separately.

Which handing should I select for a door that swings in from the left?

This unit is manufactured as a left-hand mortise lockset; choose the matching right-hand version only if the door swings from the opposite side.

What does the vestibule function mean for daily operation?

The vestibule function keeps the outside lever always locked, requiring a key for entry, while the inside lever provides free egress with no thumb turn.
