Made for the moment before chiseling

A clear outline makes the rest of the job easier to plan.

Position the guide on the door edge, score the latch-mortise outline, then move to the recess work with your hammer and chisel.

The guide combines a locating head, a 90° fence and a built-in scoring blade in one compact body—so the latch area is established before the cut begins.

A purposeful shape

Three details that do the setup work.

01 / ALIGN

90° fence

The fence braces against the door face to keep the guide square at the door edge while you position the mortise area.

02 / SCORE

Outline blade

Use the built-in 25 × 56 mm scoring blade to mark the latch-mortise outline before chiseling the recess.

03 / PREPARE

Compact ABS body

The 58 × 165 mm guide keeps the locating, fence and scoring functions together for the door-edge preparation stage.

How the guide fits into the job

Set up the mortise in four practical stages.

Follow the latch hardware instructions for your specific project. This guide supports the marking and preparation stage; the latch hardware itself is separate.

Set the fence

Seat the 90° fence against the door face and position the guide at the latch location.

Score the outline

Use the guide’s marking blade to establish the outline for the latch mortise.

Chisel the recess

Use a suitable hammer and chisel to remove material within the marked outline.

Fit the hardware

Install the latch hardware according to its own fitting instructions once the recess is prepared.

Project note: A hammer, chisel and latch hardware are required for the full installation and are not included with this guide.

Fit check before you start

For common interior door thicknesses.

Choose the guide for latch-mortise work on compatible 1⅜ in and 1¾ in doors. Confirm the latch placement and hardware instructions before beginning your project.

One focused part of a bigger project

From a marked door edge to fitted hardware.

The guide does not replace the rest of the installation. It gives you a dedicated way to line up and score the latch-mortise area before you chisel, fit the hardware and finish the door.

That keeps the tool’s role simple: help establish the right working area at the right stage.

An olive-green and black door latch installation guide for positioning and scoring the mortise area.

What does the door latch installation guide do?
