Had to replace the molding on my garage door. Watched a diy video, it's incredibly easy. Could've used an extra set of hands to help guide the strip into the rails, but since I was solo, I sprayed a little silicone lube in the rails to help move it along. Once I did that, the molding went in with no trouble. This molding is heavy duty and great for the price. Will last a very long time. Highly recommend!!
