Step 1: Start in a corner and push the barbed weather stripping into the groove. Slide the weather stripping up the groove to the corner and cut with a scissors or utility knife.



Step 3: Carefully and slowly push the router into the corner. Making sure to keep the router flat on the jam through the entire cut. Turn off the router when retracting the tool from the
groove.




Step 6: When done routing, remove the endmill or retract it into the base to protect it from accidental damage

Step 3: Test the door fit. A different diameter weather stripping might be needed depending how the door was hung and how much gap was left on each side of the door. The weather stripping should not be completely crushed/flat when the door is closed.
