The Kreg Tool KHI-CDIJ Cabinet Door Mounting Jig is a cabinet installation jig built to support and position cabinet doors while you mount hinges. This is a cabinet door mounting jig designed for installing cabinet doors accurately on face-frame and frameless cabinets. Model Number: KHI-CDIJ. If you install doors by yourself, this tool matters because it holds the door where you need it so you can focus on fastening hardware instead of fighting the door.

What makes this jig useful is not just that it supports the door, but that it helps you repeat your setup from one opening to the next. The support arm can be adjusted to nine different positions. That includes one setting for inset doors plus eight settings in 1/4 inch increments, allowing support for overlay doors up to 2 inches. In practical terms, that means you can set consistent door height and overlay without trying to balance the panel on your knee or stack random scraps under it.

The included micro-adjustment shims are where the fine tuning comes in. You can raise the door by 1/16 inch or 1/8 inch, or combine both for 3/16 inch of adjustment. On cabinet work, those small moves are the difference between a clean reveal and a door that looks just a little off. For installers, finish carpenters, cabinet makers, and serious DIY users, that adjustability saves time on fitting and refitting.

The Kreg Tool KHI-CDIJ Cabinet Door Mounting Jig is built to work with both left-hand and right-hand doors, so you are not swapping tools or changing your process as you move through a kitchen, bath, or shop cabinet run. It is also made for use with face-frame and frameless cabinet construction, which gives it good flexibility whether you are installing stock cabinets, custom built-ins, or shop storage.

Compatibility is straightforward. The jig is intended for common cabinet hinge layouts, including 1/4 inch, 1/2 inch, and full overlay applications. That makes it a practical fit for a lot of everyday cabinet door hanging work. It is not a specialty one-off setup tool. It is meant to cover the hinge and door positions most woodworkers and installers actually run into.

Who should buy it? If you install more than a couple of cabinet doors at a time, this jig earns its spot fast. It is especially useful for solo installers, remodelers, trim carpenters, and woodworkers who want more control during hinge mounting. If you only hang one door every few years, you can get by without it. If you want cleaner results, less juggling, and fewer small alignment headaches, this is exactly the kind of jig that makes the job go smoother.
