Frequently Asked Questions
- Can I install a truck cap sliding windows in cold weather?
Yes, but it's best to warm the truck cap sliding windows slightly beforehand. Cold temperatures may make the rubber less flexible and harder to manipulate during installation.
- What if I have a question that is not on this FAQ?
For anything not show here please contact Customer Service. You can also call 619-593-9483
- Will one of these work on both sliding windows on truck & cap? I don't want to remove either sliding window.
In order for the boot to attach to the vehicle there must be some sort of thin wall or flange. Keeping the slider window will cover any flange or thin wall. In short you will not be able to use any or the boots if you keep the sliding windows in place as there will be no mechanical method to install the boot.
