Frequently Asked Questions
- Can I cut the truck cap accordion seal 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 have a fiber glass camper shell. I want access to my camper shell from inside my cab but I don't want to lose heat and have a weatherproof seal. Will this product provide the right solution?
The accordion boot creates an air-tight and weather tight seal between the cabs. It does not provide any insulation. However, heat loss in minimize by the air-tight seal.
- I am getting a camper shell with a sliding glass window so I am taking the window out of my pickup and it looks like the Compression Boot would be what i need, I am wondering which is the best to get the Compression Boot - Part Number 540 or the Compression Bulb Seal - Part Number 545?
Both boot function the same. We carry both types as different cap manufacturers will use one or the other. But there are slight differences between the two styles.
The flap seal 540 is a single layer of rubber that presses against the cab. In order to seal the edge is a single straight flat edge.
The bulb seal 545 is different in this way. It has a rounded edge. the rubber is double walled with an empty cavity. The material is slightly softer and will conform to the shape of the truck.
Both seal perform similarly. When it come to which one it is really a matter of preference.
