Save time and remove the guess work when installing new doors into existing frames with the Milescraft HingeJig. This self-clamping jig comes with everything needed to rout hinge and latch mortises onto new doors.The self-clamping feature holds the HingeJig in place while routing without the use of screws or nails that can leave holes in a finished door. To use, place the mortise selector in the correct size position, set the backset plugs to the door setting, clamp, and rout. Create perfect hinge mortises in 2.5 in. 3 in. 3.5 in. 4 in. and 4.5 in. sizing on both 1-3/8 in. and 1-3/4 in. doors. Easily change between 1/4 in. and 5/8 in. radiuses by routing on different sides of the jig. Rout on the left for 1-radius, and the right for the other. Built in depth settings makes sure that you cut to the right depth every time. The HingeJig also comes with drop in templates to rout latch mortises. Remove the hinge selector, set the backset plug to latch, and drop in the template that has 1 of 3-common door latch sizes. When the job is done, snap the router bit and separately available hinge bit into the built-in storage for convenient retrieval.
