Frequently Asked Questions
- What if I’m not satisfied with my semi truck sleeper seal?srsltid=afmbooo bwyt6sjlfdhepphkboqtgmjiqfi5ls0s9vodt5v3pexbklvp?
We offer a 30-day money-back guarantee. If you're not satisfied, simply contact customer service and return the product.
- 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 am installing a boot between a truck cab and utility box.The box is about 1/2" thick. Will the boot clips expand over that type of material?
The material will not stretch that far. The maximum size that flange can be is 3/16" to receive the rubber. One solution to consider is to use flat bar and attach that around the opening in the box. One thing you must also remember - both opening need to be the same size and similar in shape.
