Disston Blu-Mol Door Latch Mortise Tool – Precise Flush Mounting for 1-3/4-in or 1-3/8-in Doors

Take the guesswork out of installing a door latch with the Disston Blu-Mol Door Latch Mortise Tool. Designed for doors that are 1-3/4 inches or 1-3/8 inches thick, this versatile tool helps you create accurate recesses quickly and with less hassle.

What sets this mortise tool apart is its attention to alignment and depth. The outline blade ensures a clean recess, while the guide post lines up with a standard 1-inch edge bore. The preset depth feature helps you stop at the right depth every time, reducing the need for rework and keeping your install clean and professional.
