Gohelper Door Hinge Jig – Aluminum Mortise Template for 2.5-5 Inch Hinges (1/4 Inch / 5/8 Inch Radius) Lock Kit

Meet the Gohelper Door Hinge Jig, a complete door hardware solution designed to help you create precise hinge mortises, drill accurate lock holes, and align latches with confidence. Built for both DIY enthusiasts and professionals, this kit streamlines installations while delivering clean, professional results that feel dependable and straightforward.

Durable, accurate construction you can trust

The jig is crafted from tough 6061 aluminum alloy, delivering greater resistance to bending and warping than common plastic templates. This rigidity helps keep mortises square and repeatable across doors. Note: this template is intended for use on the door leaf, not the jamb.

Wide compatibility and straightforward operation

Use the hinge jig on most interior doors up to 1-3/4 inches thick. It accurately mortises hinges from 2.5 inches to 5 inches long, for both 1/4 inch and 5/8 inch radius corners. For square-corner hinges, edges can be finished with minimal chiseling. A built-in depth stop guarantees consistent depth, while self-centering bits and non-slip pads help keep the setup quick, stable, and scratch-free.

• Fits interior doors up to 1-3/4" thick

Lightweight, adjustable latch and lock support
