Frequently Asked Questions
- Can I keep my sliding windows and still use a truck cap rubber seal?
Unfortunately, no. The slider windows must be removed because the truck cap rubber seal requires a clean flange or wall to attach. Sliders block access to this area.
- Can I cut the truck cap rubber seal to fit around a third brake light?
No, cutting is not recommended. Instead, remove the brake light and cover the hole, or change how the boot is mounted if you need to preserve the light.
- How weatherproof is the truck cap rubber seal?
The EPDM accordion boot creates an airtight, watertight seal when installed correctly. It's designed to keep rain, dust, and wind out — ideal for camper conversions and pass-throughs.
