Frequently Asked Questions
- How much will I need?
This material is sold by the foot. Unlike other companies that force you to buy more than you need. You get the exact amount you need. No waste. To determine how much you need measure the distance around your cab opening. It is important that both openings are exactly the same size. The average full-size pickup truck rear window opening is approximately 13 - 14 feet around. The average mini-truck is approximately 10 feet around the window opening.
- Will the Accordion Boot or Compression Boot Gasket Material work if my fiberglass shell opening is bigger than my truck window?
In order for the accordion boot to work, both openings must be the exact size. If the fiberglass shell opening is larger, use the compression boot instead.
- I have a pickup that I cut out a section between the cab and the bed. Will your product work for the metal below the window, or is that material to thin?
Yes the boot will work for this situation
