Extang Tuff Tonno Tonneau Cover

Water Resistant

Tension bows keep the cover tight across the bed and allow water to roll of the sides so no water rests on the tarp. The in-channel seal keeps the cover water tight at the rails and keeps water out of your bed.

Spring Loaded Bows

The tension bows are spring loaded which allow for easy installation and quick removal when you need more bed space.

Rear Rail

The rear rail snaps into place and pushes the cover down into the rails creating tension for a tight secure fit.

J45 Seal

The J45 seal peals on and off of the rails and snaps down tight at the rear rail giving a smooth clean look. It's the strongest tonneau attachment to date so you can be sure your gear will stay safe and dry.

Adjustable Bows

The tension bows have two different levels that they can be attached at. A higher level for colder weather and a lower level for more tension in hotter weather.
