Product Identity

The Marks USA 6A/3 is a Grade 2 sectional mortise lockset body finished in polished brass. It is configured for right-hand doors and provides an entrance function with a wide face plate. This body-only unit is designed for handleset installations in commercial or residential settings.

Compatibility Limits

The lock body works with specific Marks handleset styles including Cambridge, Crown, Grand Crown, Georgetown, Heritage, Madison, Grand Madison, Newport, Portland, Towne, Grand Towne, Claremont, Wharton, and Georgian. Several listed styles are discontinued by the manufacturer though the 6 Series body remains compatible.

Deciding Specification

The 2-3/4 inch backset determines whether this mortise body aligns with the existing door preparation. A one-inch deadbolt throw and scissor latch with anti-friction latch complete the mechanical specification.

Questions about this item

Which Marks handleset styles does the 6A/3 mortise lock body fit?

It works with Marks Cambridge, Crown, Grand Crown, Georgetown, Heritage, Madison, Grand Madison, Newport, Portland, Towne, Grand Towne, Claremont, Wharton and Georgian handlesets; those marked as discontinued may still be compatible with 6 & 8 Series bodies.

What does the Grade 2 rating mean for daily use on an entrance door?

Grade 2 indicates a commercial-duty lock tested for high-cycle durability and strength, suitable for heavy-traffic entrance doors in offices, apartments or public buildings.

How does the 2-3/4" backset and 1-1/4" x 8" face plate affect installation?

The 2-3/4" backset and 1-1/4" x 8" wide face plate match standard commercial mortise prep, so the body drops into existing cut-outs without enlarging the door mortise.
