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.
- Is there a certain glue that can be used in conjunction with the accordion boot?
The rubber boot does not require glue for installation. This is because there is a spring clip embedded it the rubber. When the boot is placed over a flange the spring clip squeezes the rubber securely. The only place you may want to glue the boot is where it meets. This is however optional. To glue the seam where the two ends meet, you can use cyanoacrylate (i.e. SuperGlue). Do not use any petroleum based glues as it will react negatively to the rubber. (i.e. rubber cement). See Installing Accordion Boot for more details.
- 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.
