Cocowin Door Hinge Jig – Precision Aluminum Template for 2.5 to 5 Inch Hinges

Overview

Meet the Cocowin Door Hinge Jig—a precision aluminum template designed for doors only. Its 6061 aluminum alloy body is precision-machined and anodized, delivering a stable platform that resists deformation and supports repeatable hinge mortises with confidence.

Designed for real world projects, the jig covers standard round hinges with 1/4 and 5/8 inch radii and accommodates square corner hinges with a chisel. The adjustable template supports hinge mortises from 2.5 to 5 inches in length and adapts to both thicker hinges (4.5 and 5 inches) and thinner ones (2.5, 3, 3.5, 4 inches). It fits most doors up to 1.75 inches thick and is intended for doors only, not jambs.

What’s included in the kit

• Door hinge mortise template
• Router bit (1/2 inch shank, heat treated tungsten steel blades)
• Self centering hinge bit with automatic centering
• PH2 SL6 double ended driver bit
• User manual

Key features that support clean, repeatable cuts

• Durable construction: precision machined 6061 aluminum with anodized coating for deformation resistance versus plastic alternatives
• Non slip handling: integrated silicone pads secure the jig while protecting the door finish
• Integrated depth gauge for consistent hinge depth across hinge thicknesses
• All in one kit: includes essential shank adapters and bits for quick setup
• Ease of use: intuitive setup aims to deliver professional results for both DIYers and pros

Real world use cases and benefits

• Interior door projects where consistent hinge mortises speed up installation and reduce guesswork
• Repairs or replacements that maintain hinge alignment and consistent door swing
• Projects involving standard and square corner hinges, with a setup that adapts to multiple hinge sizes
• A compact, all in one kit that minimizes tool clutter and streamlines workflow on site

Notes and compatibility

Not designed for door jambs. For doors up to 1.75 inches thick, the jig provides a reliable framework to create precise mortises without guesswork.
