Frequently Asked Questions
- What is the minimum corner radius I can use?
The recommended minimum radius for corners is 1 inch. Tighter corners may cause the truck sleeper boot accordion to bunch or kink.
- 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.
- 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.
