Frequently Asked Questions
- Is professional installation recommended for a semi truck box to cab weather seel?
Most DIYers can install it successfully, but if you're unsure or working with custom cuts, a professional installer may help ensure a perfect fit.
- Is there a certain glue that can be used in conjunction with the accordion boot?
The rubber boot does not require glue for installation. This is because there is a spring clip embedded it the rubber. When the boot is placed over a flange the spring clip squeezes the rubber securely. The only place you may want to glue the boot is where it meets. This is however optional. To glue the seam where the two ends meet, you can use cyanoacrylate (i.e. SuperGlue). Do not use any petroleum based glues as it will react negatively to the rubber. (i.e. rubber cement). See Installing Accordion Boot for more details.
- 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.
