Frequently Asked Questions
- How much sealing a truck capdo I need?
This material is sold by the foot. To determine how much sealing a truck cap you need, measure the full distance around your cab or window opening. Most full-size pickups need about 13–14 feet, while mini-trucks average around 10 feet.
- What if the camper shell opening is larger than my truck window?
If the shell opening is larger, the sealing a truck cap may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations.
- Can I keep my sliding windows and still use a ?
Unfortunately, no. The slider windows must be removed because the sealing a truck cap equires a clean flange or wall to attach. Sliders block access to this area.
