Here’s a very accurate and fast way to install Glynn-Johnson FB61 or Ives FB41 series automatic flush bolts in wood doors. Our router guide uses a plunge type router and will turn a long job into one that is both quick and easy. This is a two part guide. The main guide is used to cut the faceplate on the door top or bottom and front. Attaching the second template will guide the router to cut the body mortise. Just square the corners with a chisel and the job is done! This template attaches with screws on the door top and front. A c-clamp can also be used instead of a screw for the front. This tool will work on 1-3/4”, 2” or 2-1/4” thick doors. It requires a plunge router with a 5/8” OD template guide and 1/2” diameter bit. FOR WOOD DOOR USE ONLY.
