If you’ve ever wanted to create a clean, sealed pass-through between your truck cab and camper shell (or custom sleeper), then you’ve probably run into the problem of the gap. That awkward, leaky, dust-collecting space that sits between your rear cab and topper.
That’s where the accordion boot comes in — a flexible rubber seal designed to bridge that gap and give you pas through access.
What Exactly Is an Accordion Boot?
An accordion boot is a rubber bellows-style seal that connects the rear window opening of your truck cab to the front window opening of your camper shell, canopy, or sleeper. Think of it like a flexible tunnel that lets you:
- Pass through from cab to camper
- Keep out dust, wind, rain, and road noise
- Maintain climate control
- Preserve pressure and airflow for vents or fans
It’s called an “accordion” boot because of its ribbed, flexible design—it compresses and expands like an accordion to fit various gap sizes.
Why Do People Use an Accordion Boot?
People who install accordion boots usually fall into one of three groups:
1. Overlanders and Box Trucks
If you’re using your truck for camping or long-haul travel, a sealed pass-through is a game changer. It lets you:
- Move freely from cab to camper without going outside
- Stay warm and dry in rough weather
- Pass gear through easily
2. Work Trucks or Mobile Businesses
Need secure access between your cab and service area or sleeper? An accordion boot keeps your equipment safe from the elements and lets you monitor or access gear without leaving the cab.
3. Custom Campers
Some folks build out custom living spaces in the truck bed. An accordion boot connects the living area with the cab—creating a compact RV-like setup.
4. Semi Tractor Sleepers (Replacement Boots)
Accordion boots are also commonly used on semi trucks with sleeper compartments. Over time, the original cab-to-sleeper boot can become cracked, brittle, or leaky. Our accordion boots offer a universal fit replacement for many semi-truck models, restoring a weatherproof, flexible connection between the cab and sleeper.
How Is It Installed?
Installation is relatively simple with basic tools and a little patience. Here’s a quick overview:
- Clean the surfaces on both the cab and the camper shell.
- Attach the boot using the integrated spring steel clip or fasteners (depending on your model).
- Test the seal for leaks and adjust if needed.
Most installs take under an hour and don’t require any permanent modifications.

Will It Work on My Truck?
Accordion boots are compatible with most pickup trucks and canopies as long as:
- Both your truck cab and camper shell the exact same side window opening.
- They are aligned closely to each other.
- The gap is not excessive (typically 2″–7″)
If you’re unsure, feel free to contact us and we’ll help you confirm compatibility.
