Install a BestRail Channel System onto your truck bed rails to open up a world of possibilities for accessorizing the bed.

The Channel System clamps easily onto your truck bed rails and requires no drilling for installation. The built-in channels on the rails allow you to mount a large number of system-specific accessories (sold separately) and build a fully integrated cargo management system.

The Overhead Rack mounts onto the rails and creates a ladder rack for your truck bed. The rear support of the Overhead Rack slides along the rails to reposition and accommodate short or long loads. It also slides to the front of the cab to reduce drag and wind noise, and it doubles as a framing support for particularly tall loads.

Ladder Rack Extensions are available in 10' and 12' applications and install on the Overhead Rack for longer loads that require over-the-cab support. The Extensions also serve as load stops for items mounted on the Overhead Rack.

A Headache Rack also works in conjunction with the Overhead Rack. Not only will it protect the rear window from shifting cargo but it provides shade as well.

The BestRail Soft Tonneau installs easily using the Channel System and provides protection for your cargo in all temperatures.

The Hard Tonneau comes with three panels that can be removed independently for easy access to your cargo whenever you need it. The Hard Tonneau also gives you lockable storage with the addition of coupler locks (sold separately).

A Tonneau Storage Tray slides into the BestRail Channels to help organize your gear. It works great with a tonneau cover as the cover will help keep items in place. The shallow design of the trays (only 8" deep) also allow for plenty of truck bed space beneath the bin for lumber or other bulky items.

The Bestrail system also has two types of tie down mounts that are easily accessible at the truck bed rail height. Tie-Down Anchors slide into the BestRail channels and secure with a hand knob, providing a place to attach standard straps for cargo control. Retractable Tie-Downs mount anywhere along the BestRail channels and offer a strap-and-hook option for securing your cargo.
