Frequently Asked Questions
- Is the truck capswindow seals reusable if I remove it?
While technically reusable, removal often deforms the material or compromises the embedded clip, so we recommend replacing it if removed.

Basic tools like a utility knife, heavy duty siccors, measuring tape, a soft mallet, are usually sufficient for installing a truck capswindow seals.
- I am installing a boot between a truck cab and utility box.The box is about 1/2" thick. Will the boot clips expand over that type of material?
The material will not stretch that far. The maximum size that flange can be is 3/16" to receive the rubber. One solution to consider is to use flat bar and attach that around the opening in the box. One thing you must also remember - both opening need to be the same size and similar in shape.
