[Integrated Door Hinge Mortise] Our door hinge installation kit is a convenient accessory 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 adjusts to different hinge lengths, thicknesses, and corner types (rounded or square). It includes a built-in depth gauge for accurate depth setting and a self-centering hinge drill bit to ensure precise screw hole placement. Angle pieces are included for marking hinge positions with different radii. Note: This tool is designed 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 cleanly and accurately. (Router not included.) The routing area is clearly marked on the outer wall of the template. Use the router depth gauge to set the depth, then rout the hinge recess from the template area.
