Frequently Asked Questions
- Does the pickup truck cap window bootrequire glue to install?
No glue is required. The pickup truck cap window boot 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.
- Can I keep my sliding windows and still use a pickup truck cap window boot?
Unfortunately, no. The slider windows must be removed because the pickup truck cap window boot requires a clean flange or wall to attach. Sliders block access to this area.
- Will the pickup truck cap window boot work on a walk-through truck conversion?
Yes! This is a perfect use case. The pickup truck cap window boot allows you to join the truck cab and camper shell or utility box with a weather-sealed, flexible connection.
