[Integrated Door Hinge Mortise] Our door hinge installation kit is designed for cutting and installing door hinges with round or square corners, featuring two removable plastic inserts. [Easy to Install and Use] The hinge router template allows adjustment of hinge length, thickness, and corner type (rounded or square). It includes a built-in depth gauge for accurate depth setting and comes with a self-centering hinge drill bit for precise screw placement. Angle guides are included for marking hinge positions with different radii. Note: This tool is intended for use on doors only, not door frames. [No Hammer and Chisel Required] Use this hinge template with a router or compact router to install door hinges. (Router not included.) The routing area is located on the outer wall of the template.
