    Looking for a durable and stylish snap cover? Want to have easy access into the front of your truck bed? The BlackMax tonneau cover was meant for you. This tonno combines a bold, all-black look with the all-around versatility. Its frame is constructed from heavy duty black rails and bows to give the cover additional strength and to make sure it looks as good as it performs. Extang's MaxSnaps are on all four sides allowing the front corner to be unsnapped for quick loading. This is great for access to the front section of the cab, without having to unfasten the entire cover. What also makes Extang's snap covers that much unique is that these are the only patented fully adjustable tonneau covers performing equally great in cold and hot climates.

    extang black max tonneau cover

    Featuring famous Extang engineering, the cover is constructed to ensure maximum service life. Every detail, from the fiberglass reinforced MaxSnaps to the anodized aluminum frame and vinyl tarp, was crafted to make this tonno the most sturdy and elegant cover on the market. The black vinyl tarp rests over the Monster Bows that are spring-loaded for fast and easy installation. To adjust the position of the bows, simply push and hold on one end and let the other end slide on using the spring action. And using TuffKlamps, you can also adjust the bow height: choose high position for maximum water shedding and improved mileage, or low position for a sleek, low-profile look and easy cold-weather attachment. The TuffKlamps are easy-to-use and work great with bed liners.

    To make sure the edges and corners will lie smooth in any weather and the snaps will never rip out, the snaps and corners are backed with thick polymer. And for the snaps to stay on the rail when the tarp is rolled up, the cover features SnapStoppers. Even though the snaps and tail rail reliably secure the tarp, you can easily disengage the tail rail by pulling the LeverLock corner system. You can then roll up the cover and secure it with Hook and Loop straps. Proudly made in the USA, the cover is extremely durable and comes with a lifetime warranty on the frame and 10 years on the tarp.

    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.
