Frequently Asked Questions - Accordion Rubber Boot Replacement
Frequently Asked Questions
- How much accordion boot do I need?
This material is sold by the foot. To determine how much accordion boot you need, measure the full distance around your cab or window opening. Most full-size pickups need about 13–14 feet, while mini-trucks average around 10 feet.
- Does the accordion boot require glue to install?
No glue is required. The accordion boot has a spring clip embedded in the EPDM rubber that clamps onto a thin flange. You can optionally glue the seam using cyanoacrylate (SuperGlue), but avoid petroleum-based adhesives.
- What if the camper shell opening is larger than my truck window?
If the shell opening is larger, the accordion boot may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations.
- Will the accordion boot work with thin metal or wood frames?
Yes, but there must be a flange no thicker than 3/16". For wood or thick materials, add a metal strip (like aluminum flat bar) around the opening for the accordion boot to grip.

- 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.

You will not be able to attach the boot material to the wood, It is too thick. The best way to remedy this is to add a flange to the box. This could be done with steel or aluminum flat bar, or something similar (i.e. sheet metal, fiberglass), installed around the perimeter of the opening to allow the boot to attach to the box
- I have a Ford F150 with a LEER top. I an pretty sure the accordion seal is the correct option but the warning that the opening must be an exact match has me concerned.

The accordion boot only stretches one direction. There is a metal clip embedded in the rubber that allow you to attach the boot to the fiberglass/sheet metal, Therefore both window openings must be the same size. If the opening in the shell is smaller you can cut and trim the fiberglass to match the truck's window opening.

- I have a truck that I want to install a camper shell on. The shell has a slider and I will need to remove the rear cab window. Is there a procedure when using a boot that insures a watertight seal?
To insure a water tight seal you should consider the accordion boot. In order to use the accordion boot there are a few condition that need to be met.

- 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. - Can you make the accordion gasket in different colors?
Sorry the boot only comes in black. We have never tested it, but the rubber is epdm and with the right paint is can be colored. From the research the recommended paint should be an acrylic coating specifically designed for epdm rubber. Usually this is paint for roofing. Latex paint should be avoided.
- What do you recommend is the smallest radius cut out in the corners of the opening?
The recommended minimum radius is 1 inch for the boot for corners.
