One finger removal

The BlackMax corners feature Extang’s impressive new “LeverLock™” attachment. Pull back the lever and the tail rail unlocks and quickly disengages for bulk hauling. When the lever latches you know it’s locked. “LeverLock™” securely stays in place and will not vibrate loose. All this with one finger!

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.

Quick access to front of truck bed

Quickly place items in the bed near your cab door, snap on the tarp, jump in and go!

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.

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.

Your tarp can be quickly rolled up and secured with strong convenient straps allowing you to haul large items.
