U.S. PATENT NOS. 10,124,656 & 10,118,472

The first truck bed cover
that keeps working
when you need it most.

Every other folding cover steals your rails the moment it opens. RAIL keeps them clear. Ladder racks. Cab guards. Accessories. All on.

THE PROBLEM

Every tonneau cover on the market makes you choose.

Cover or Rack.

Every folding tonneau uses the bed rails as its mounting points. The moment you fold it up, those rails are blocked. No ladder rack. No cab guard. No accessory mounting.

Remove or compromise.

Contractors and overlanders need both. Most settle for covers that don't work with their racks, or racks that limit their cover options. Nobody wins.

T-slot workaround.

Some covers offer T-slot rails on top of the cover itself — but they raise the mounting point, reduce ground clearance, and don't work for cab guards that need the OEM rail position.

"I've been looking everywhere for a ladder rack that works with my tonneau cover.
Every option either blocks the fold or requires full removal."
— Every truck owner with a folding cover
HOW RAIL WORKS

A hinge system that folds differently.

RAIL's patent-pending mechanism folds the cover panels toward the cab without consuming the bed rail mounting channel. The rails stay clear at the factory position — full stop — so every standard accessory clamp and mount works without modification.
01

Rail-preserving fold geometry

Panels fold forward into a low-profile position against the cab bulkhead, pivoting on a rail system that sits below the OEM bed rail mounting channel. The rails themselves are never blocked.

02

Integrated tie-down channels

When folded, the cover's structural edge doubles as a tie-down anchor point. The rail profile stays clean and accessible for any clamp-on accessory — ladder racks, cargo bars, roof-top tents.

03

Lockable, weatherproof, secure

Full perimeter sealing. Tailgate auto-latch. 400 lb. rated. Three driving positions. No compromises on the core cover functionality — the rail preservation is a feature, not a trade-off.
