Corners securely attach

An easy pull disengages your tail rail for bulk hauling. To resecure: slide and click, your tail rail is locked in place. You’ll be impressed with CLICKLOCK’s high quality spring loaded stainless steel ball bearings that click into place with such a satisfying feel.

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!

Quicker installation

Our TUFFKLAMPS™ simply drop into the rail channels (works well with bed liners). Easy on. Clamps tight.

The Best Tonneau Warranty

Ten year tarp and lifetime frame—the best in the industry. Longer than most folks will own their truck! It’s more than enough coverage.

Snaps are your tonno’s most important part

Fiberglass reinforced nylon formula makes the BlackMax’s snaps strong and durable. Tested and proven under intense usage for years in the lab and field. Extang’s patented “MAXSNAPS™” will not break.

Extang’s SNAPSTOPPER™ is a small detail that means a lot. Roll up your tonneau tarp, carry a large load and the snaps will stay on the rail.

Bow height adjustment

Extang’s Monster Bows™ quickly spring on and off with no tools. It’s fast and easily done with one hand. The TUFFKLAMPs™ allow two bow heights: HIGH for maximum water shedding in harsh weather, and for improved gas mileage. LOW for sporty good looks and cold weather tonno attachment.

Extang makes the ONLY tonnos that work well in cold climates

• Stud low for tight fit in hot weather
• Slide off, flip over, then slide on again
• Stud high for looser fit in cold weather
