Frequently Asked Questions
- Will the lepac window boot work with thin metal or wood frames?
Yes, but there must be a flange no thicker than 3/16". For wood or thick materials, add a metal strip (like aluminum flat bar) around the opening for the lepac window boot to grip.
- How long will my lepac window boot last?
EPDM rubber is extremely durable, UV-resistant, and built to last for years. Proper installation can extend its lifespan significantly.
- I am wondering if the compression boot can be trimmed to fit around the third brake light?
You cannot cut the boot to fit around the 3rd brake light. Here are a couple of things you may want to do.
- Remove the brake light and cover the opening with a thin plate.
- Instead of installing the boot to the shell, install the boot into the truck window opening. Do this only if you remove the rear window.
