Frequently Asked Questions
- What if the camper shell opening is larger than my truck window?
If the shell opening is larger, the topper window seals may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations.
- What’s the difference between the flap and bulb compression boot?
The flap version has a straight edge, while the bulb version includes a rounded, softer cushion for enhanced sealing and flexibility.
- I have a truck with a wood framed utility box and would like join the cab and box using the accordion boot. How to I attach the boot?
You will not be able to attach the boot material to the wood, It is too thick. The best way to remedy this is to add a flange to the box. This could be done with steel or aluminum flat bar, or something similar (i.e. sheet metal, fiberglass), installed around the perimeter of the opening to allow the boot to attach to the box
