Right-Hand Mortise Storeroom Lock

The Tuff Stuff 5100DWR is a heavy-duty mortise lockset designed for commercial and residential doors that must stay locked from the outside at all times. Its vestibule function operates with a latch only, omitting a deadbolt and rocker mechanism. The lock is handed specifically for right-hand door swings.

2-1/2 Inch Backset Fit

The single specification that decides compatibility is the 2-1/2" backset measurement. This distance from the door edge to the centre of the knob spindle must match the existing door preparation exactly. A different backset will prevent the lock case from aligning with the bore holes, making installation impossible without modifying the door.

Surface-Mounted Brass Trim Included

The lockset ships with solid brass surface-mounted plate assemblies and screw-on knobs fitted with a swivel spindle. These components provide the complete external and internal trim needed for immediate fitting. A solid brass cylinder and two keys are also supplied, so the lock can be keyed into an existing system or used standalone without extra parts.

Questions about this item

What does the 2-1/2" backset mean for door preparation?

The 2-1/2" backset sets the centre of the knob 2-1/2 inches from the door edge, so the mortise pocket and cross-bore must be drilled to that dimension for the lock body to sit correctly.

How does the mortise interface limit the lock's operation?

The mortise body fits inside a pocket cut into the door edge; the face plate measures 1-1/16" x 7-5/8" and the latch-only function means the lock never projects a deadbolt, only the spring latch.

What physical space and hardware are needed to mount this lockset?

A door thick enough for a mortise pocket, a 1-1/16" x 7-5/8" face-plate cutout, 2-1/2" backset bore, and surface-mounted brass plates with screw-on knobs on both sides.
