Frequently Asked Questions
- Can I cut the rear window pass through camper shell to fit around a third brake light?
No, cutting is not recommended. Instead, remove the brake light and cover the hole, or change how the boot is mounted if you need to preserve the light.
- I`m about to put a a fiberglass shell on the back of my truck and I`m taking out the back window. I think the fiberglass shell opening is a bigger than the the back window of the truck. will the Accordion Boot or Compression Boot Gasket Material work?
In order for the accordion boot to work in your application both opening must be the exact size. If the opening in the fiberglass shell is smaller you have the option of resizing the opening to fit your rear window opening. If the opening in the fiberglass shell is bigger than the opening in your truck's window opening you are limited to using the compression boot.
- Will one of these work on both sliding windows on truck & cap? I don't want to remove either sliding window.
In order for the boot to attach to the vehicle there must be some sort of thin wall or flange. Keeping the slider window will cover any flange or thin wall. In short you will not be able to use any or the boots if you keep the sliding windows in place as there will be no mechanical method to install the boot.
