Frequently Asked Questions
- How do I measure for an accordion boot?
Use a flexible measuring tape to trace the perimeter of the pass-through opening between your cab and camper.
- Can I cut the accordian boot cap 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.
- Can I install a accordian boot cap in cold weather?
Yes, but it's best to warm the accordian boot cap slightly beforehand. Cold temperatures may make the rubber less flexible and harder to manipulate during installation.
