Frequently Asked Questions
- Does the accordion seal for semisrequire glue to install?
No glue is required. The accordion seal for semis has a spring clip embedded in the EPDM rubber that clamps onto a thin flange. You can optionally glue the seam using cyanoacrylate (SuperGlue), but avoid petroleum-based adhesives.
- What if the camper shell opening is larger than my truck window?
If the shell opening is larger, the accordion seal for semis may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations.
- Do I need glue to install the accordion boot?
The rubber boot does not require glue for installation. It has a spring clip embedded in the rubber. When the boot is placed over a flange, the clip squeezes the rubber securely. The only optional gluing is at the seam using cyanoacrylate (SuperGlue). Avoid petroleum-based adhesives like rubber cement.
