Frequently Asked Questions
- Does the sleeper boot gasket require glue to install?
No glue is required. The sleeper boot gasket 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 sleeper boot gasket may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations.
- Will the sleeper boot gasket work on a walk-through truck conversion?
Yes! This is a perfect use case. The sleeper boot gasket allows you to join the truck cab and camper shell or utility box with a weather-sealed, flexible connection.
