Frequently Asked Questions
- What type of rubber is used in your boots?
Our boots are made from high-quality black EPDM rubber, known for its durability, UV resistance, and flexibility across extreme temperatures.
- Can I install a sliding glass window donut in cold weather?
Yes, but it's best to warm the sliding glass window donut slightly beforehand. Cold temperatures may make the rubber less flexible and harder to manipulate during installation.
- I have a Ford F150 with a LEER top. I an pretty sure the accordion seal is the correct option but the warning that the opening must be an exact match has me concerned. It looks like the truck opening is larger at the lower corners but until the window is removed, who knows? Am I on safe ground getting the accordion seal for this application?
The accordion boot only stretches one direction. There is a metal clip embedded in the rubber that allow you to attach the boot to the fiberglass/sheet metal, Therefore both window openings must be the same size. If the opening in the shell is smaller you can cut and trim the fiberglass to match the truck's window opening.
