Unique peel on & off gives you great looking smooth edges
Easy attachment
Pulling out with one hand while pressing down with the palm of the other hand securely attaches the cover to the tonno frame.
Tarps designed for strength & good looks
Corners don’t buckle up due to parachute grade nylon corner reinforcements. Snaps & corners are backed with thick polymer forcing the corners and edges to lie smooth and look good in any weather. The thick polymer edging also keeps your snaps from ripping out!
Rotating rear rail allows tarp to tighten snugly
Great Extang Engineering is hard at work hrelease, liftere. You simply release the levers on both corners, tilt rear rail up, hook tarp in the rail’s groove and click it down. You can feel the “snap” effect and see the tarp tighten snugly.
Bows will never fall off
The MONSTER BOWS™ ends are sdiagram of Monster Bowspring loaded for easy installation. They will never fall off at any speed or even with the roughest driving conditions. Simply push and hold on one end and let the other end slide on using the spring action. They are Extang engineered for simplicity, speed of install and everyday convenience and confidence.
