Gohelper LLT1062US Door Hinge Jig Kit with Aluminum Jig and Lock Templates

If your door project calls for routed hinge mortises as well as lock and latch cutouts, this kit brings those tasks together. The aluminum hinge jig is designed for door leaves, while the included plastic templates cover common wooden-door lock and latch setups. It suits a DIY installation where you want one coordinated set of guides rather than separate tools for each hardware step.

For a single hinge-routing task, a hinge-only jig may be all you need. This set makes more sense when the project also includes installing a lock and latch.

Quick sizing guide

The hinge jig fits most interior doors up to 1-3/4 inches thick and handles hinge lengths from 2-1/2 to 5 inches. It supports 1/4-inch and 5/8-inch radius round-corner hinges. With square-corner hinges, the router leaves rounded internal corners, so some chiseling is needed to finish the mortise edges. The jig is intended for the door leaf, not the jamb or frame.

The adjustable lock template is described for wooden doors that are 1-3/8 or 1-3/4 inches thick, with 2-3/8- or 2-3/4-inch backsets. The latch installation tool is also listed for doors with those two thicknesses. These ranges help narrow down whether the included guides match your door and hardware before you begin.

What you’ll notice day to day

The hinge jig is made from 6061 aluminum and has an anodized finish. A built-in depth stop is intended to help keep hinge mortises consistent, while self-centering bits and non-slip pads support positioning during setup. The lock template is plastic and adjustable, making the kit a mix of a metal hinge guide and lighter templates for the other hardware tasks.

The set includes a hinge mortising jig, router bit, self-centering hinge bit, double-ended screwdriver bit, lock installation template, two hole saw kits, an arbor with pilot drill, a door latch installation kit, and three user manuals. That breadth is useful when replacing or fitting several pieces of door hardware, someone only cutting hinge mortises may have little use for the lock and latch components.

Buyer feedback is generally favorable about ease of use, the aluminum construction, and the jig’s usefulness for DIY projects. Opinions on accuracy and adjustability are less consistent: some buyers find setup accurate and straightforward, while others report alignment or adjustment concerns. Worth considering if your door and hardware fall within the listed ranges and you want hinge, lock, and latch guides in one set. Not the best choice if you need a jig for the jamb or frame, since the manufacturer explicitly excludes those surfaces.

Is it worth it?

This Gohelper kit is best suited to a project that combines hinge mortising with lock and latch installation on a door leaf. Its stated hinge range and door-thickness coverage offer useful selection checks, and the included templates bring several hardware steps into one kit. If you only need a hinge guide, a simpler hinge-only setup may be a closer match, if the job involves the jamb or frame, this jig is not designed for that work.
