When opting for a roll-up cover, what is the very first feature you're thinking about? Sure, the tonno must open in seconds. And that is exactly what Extang's Express tonneau cover was engineered for. Thanks to the quick-release levers located at the tail rail and cab you get instant and full bed access. You only need to drop the tailgate and lightly press the Quick Lever to release the tail rail. After the tarp is rolled up, you can fasten it at the cab or remove it by releasing the Quick Lever that's located at the cab.

However, ease of usage is not the only benefit you get with the Express cover. Because this tonno features all-weather tapered design and comes fitted with the WeatherTuff sealing system, it will reliably protect your truck bed and cargo from the elements. WeatherTuff is a dual sealing system integrated along the underside of the tarp that secures together with a fin seal along the side rails. The cover comes with the triple-stitched black vinyl tarp that will look great in all weather conditions and fit tight because of the automatic self-adjusting tension system.

Another advantage of this cover is that it's designed to fit your truck bed even if you already have a toolbox installed. It can accommodate any standard 20'' toolbox no matter what brand, and the L-Channel sealing will provide a water-tight seal against the toolbox. This tonno is also amazingly easy to install thanks to the aluminum rails that are pre-drilled for no-measure clamp installation. The low-profile clamps can be hidden out of the way as the cover boasts unique side rail design. And for you to have no loose to store, the black anodized bows are pre-positioned and roll-up with the cover. Be sure, the cover will fully protect your cargo - the industrial style, high peel strength hook and loop fastenerswill make sure the cover stays in place no matter what. Last but not least, you can be absolutely sure in the highest quality of the Express roll-up cover because it is 100% made in the USA and backed by the Maximum Strength lifetime warranty.

Lifetime Frame & Tarp: The Revolution Tonno, Express Tonno, Trifecta and eMAX Tonno carry a lifetime warranty against defective materials or workmanship on all tonneau rails, aluminum components, clamps, bows, hardware and vinyl covering.

Lifetime Frame & 10-Year Tarp: The Classic Platinum, BlackMax, FullTilt and Tuff Tonno carry a lifetime warranty against defective materials or workmanship on all tonneau rails, aluminum components, clamps, bows, hardware. And a 10-year warranty against defective materials or workmanship on the vinyl covering.

The Solid Fold and EnCore carry a three-year warranty against defective materials or workmanship on all tonneau rails, aluminum components, clamps, bows, hardware.

This warranty is against defective materials or workmanship. The warranty is void if the product has been damaged by accident, unreasonable use, neglect, improper service/installation/removal, modifications, acts of God, normal wear and tear or other causes not arising out of defective materials or workmanship. Consequential and incidental damages are not covered under this warranty.

Wind whip damage: Tarps must be secured at all points when vehicle is in motion. An unsecured tarp will flap, resulting in damage to the fabric.

Improper cleaning: It is recommended to use the tested and approved Extang Tonno Tonic or clean with soap and water only. Do not use vinyl conditioners (i.e. Armor All) because they will shrink the vinyl.

Overloading of cargo: Cargo should not touch the tonneau at any point. Protrusions in the tarp will stress the fabric. Cargo may shift while traveling and cause it to push against the fabric or panels and damage it.

Driving with panels open or improperly secured on all folding tonneaus: Prior to vehicle operation, clamps must be tightly secured so that clamp lips tightly grip the inner bedside metal surface. Open position: Tonneau must be completely folded and secured with BOTH buckles. Closed position: Tonneau must be completely flat and secured at all 4 clamps.

Opening panels without removal of debris on all folding tonneaus: Top of tonneau MUST be free of foreign material including snow and ice before opening panels or severe damage may result.

Towing: Do NOT tow your vehicle from the rear with any Extang tonneau cover on your truck.

The warranty applies to the original consumer/purchaser. Warranty registration must be on file and/or proof of original purchase (detailed and dated receipt) required for warranty to be effective. Warranty coverage starts from the date of purchase.

PERFORMANCE: Provided all warranty conditions are met, Extang will either repair or replace (at Extang's option) the product or component. This warranty gives you specific legal rights and you may also have other legal rights which vary from state to state.

Magnuson-Moss Warranty Act:
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) Learn More

Express Tool Box Tonneau Cover
First I did not know a tool box Tonneau Cover even existed. I was so pleased after searching on the internet to discover this one. The ease of installation was amazing. I installed it in less then 10 minutes. The quality is better then I expected. This is a fabulous product that I highly recommend.

Express Tool Box Tonno Roll-Up Tonneau
I got the cover for Father's Day and it really looks good. I was able to install cover pretty easy after reviewing step by step instructions and actually laying it out before removing tape. So far I don't have any complaints and it offers protection and coverage for items that I place in the truck bed. I will say that I have a low profile toolbox so my latches are underneath the cover so I have to either roll-up the cover or lift one side for access. Otherwise very satisfied.
