I had to install by myself when it was cold outside. I used a spray bottle with soapy water for lube and a heat gun to soften the strip. 1st 4x went on easy, next 10x was 2\" at a time, the last 4' slid right on. Admittedly it was a cramped space on starting end so I could only line up a foot at a time feeding it in. But it is thicker with better sealing than oem. It should keep the mice and pack rats from munching thru & getting into the garage.
