Frequently Asked Questions
- Can I cut the seal between truck cab and cap to fit around a third brake light?
No, cutting is not recommended. Instead, remove the brake light and cover the hole, or change how the boot is mounted if you need to preserve the light.
- Is the seal between truck cab and cap reusable if I remove it?
While technically reusable, removal often deforms the material or compromises the embedded clip, so we recommend replacing it if removed.
- Do I need glue to install the accordion boot?
The rubber boot does not require glue for installation. It has a spring clip embedded in the rubber. When the boot is placed over a flange, the clip squeezes the rubber securely. The only optional gluing is at the seam using cyanoacrylate (SuperGlue). Avoid petroleum-based adhesives like rubber cement.
