  • Surface finishPolished Brass

Product Identity

The Tuff Stuff TUF120 is a surface-mounted rim night latch in polished brass. It combines a deadlocking spring latch with a single cylinder so the door locks automatically when it closes. The latch hold-back button keeps the bolt retracted when you do not want the door to lock behind you. Installation requires only a 1-1/4 inch bore and suits doors from 1-3/8 to 2-1/2 inches thick.

Who This Suits

This lock suits homeowners who want a traditional brass night latch that secures the door without a key on the inside. The SE1 keyway and two included keys work for standard key-alike requirements. It is not for installers who need a mortise lock body, a double-cylinder deadbolt, or a latch that accepts a different keyway profile.

Deciding Specification

The 1-1/4 inch bore diameter is the single specification that decides fit. If the door already has a different hole size or a mortise pocket, this latch cannot be installed without new drilling.

Questions about this item

How is the 1-1/4" bore drilled for this surface-mounted lock, and what step is often missed?

Drill a 1-1/4" diameter hole through the door face; the common miss is forgetting that no mortising is needed because the lock body sits on the surface.

Which parts of the TUF120 will need replacement over time?

The 5-pin tumbler cylinder or the SE1 keys may wear; the die-cast brass body and angle strike bracket typically last the life of the door.

What is the first limitation when the slam lock is used repeatedly on a busy door?

The spring-latch mechanism can fatigue, causing the automatic deadlocking action to become sluggish or fail to engage fully.
