Measure Your Truck Bed for a Tonneau Cover

Does your truck have a track system?

Preserve your cargo with the easy to use Rugged E-Series tri-fold tonneau cover. This cover is perfectly designed to keep out prying eyes and weather.

The Rugged E-Series tri-fold is designed with a durable tear-resistant vinyl supported by an aluminum frame that allows heavy rain or snow to simply slide off. Fully surrounding this aluminum frame is a seal that prevents moisture from entering the bed. When the cover is open all the way, it has fastening straps that will keep the cover secured while driving.

The Rugged E-Series tri-fold tonneau cover comes fully assembled and installs without tools in less than five minutes. With the quick latch system it will only take you a few seconds to open it up, so you can stow your cargo.

Rugged backs this truck bed cover with a limited lifetime warranty, so you are covered as long as you own it.

Order Notes

The cargo management, utili-track, or deck rail system options refer to the factory installed rail system designed to hold moveable cargo cleats along the inside of your truck bed. Please call us for further clarification.
