Product identity and intended use
This Marks USA 6DW/3 mortise lockset body is a Grade 2 sectional unit finished in polished brass and configured for right-hand doors. It is designed for vestibule or storeroom functions where the outside lever is always locked and entry is by key only. The body fits Marks handleset styles such as Crown, Towne and several discontinued designs.
Practical limits of the mortise interface
The lock body uses a 2-3/4 inch backset and a wide front face plate measuring 1-1/4 by 8 inches. Operation relies on a scissor latch combined with an anti-friction latch; no deadbolt or rocker mechanism is included. There is no interior thumb turn, so the lock cannot be unlocked from inside without a key.
Compatibility checks before ordering
Verify that your door preparation matches the 2-3/4 inch backset and the 1-1/4 by 8 inch face plate cutout. Confirm the door swing is right-hand so the latch orientation is correct. Ensure the existing handleset trim is one of the compatible Marks styles listed, as other brands or designs will not align with this body.

Questions about this item
Is the 6DW/3 body compatible with my existing Marks handleset trim?
This lock body fits Marks handleset styles including Cambridge, Crown, Grand Crown, Georgetown, Heritage, Madison, Grand Madison, Newport, Portland, Towne, Grand Towne, Claremont, Wharton and Georgian; many are discontinued but the 6 Series body still works with them.
What does the vestibule storeroom function mean for daily use?
The lock is always locked from the outside and requires a key for entry; there is no interior thumb turn, so the inside lever always retracts the latch for free egress.
How does the 2-3/4" backset and 1-1/4" x 8" faceplate affect installation?
The mortise pocket must be cut for a 2-3/4" backset and the wide 1-1/4" x 8" front plate; verify your door prep matches these dimensions before fitting the body.
