You can also set the router to a pre-cut hinge mortice to allow the strip to sit in line with the leaf edge.
The door is laid flat for the routing operation making it a very simple task. Ensure the door is secure and stable before any routing operation.
Place the router onto the door, check the cutter is projecting correctly and rout the edge.
When routing a door with hinge recesses already cut, ensure the recesses are facing downwards when routing so that the bearing has full contact with the door edge. If the door is routed with the hinge recesses uppermost the bearing guide will drop into them, leaving a deeper groove in these areas.
The resulting groove will now be at the correct depth and perfectly parallel to the door face allowing the strip to fit flush
