Unsurpassed Toughness
The Diamondback HD can support up to 1600 lbs of weight on top, more than any other tonneau cover available. The .100-inch thick aluminum panels can be equipped with cargo cleats that provide several tie-down locations for anything you need to haul. DiamondBack offers an optional black coating that protects the cover from dents, dings, and scratches.
Opens At The Front And Rear
Front and rear opening panels give you the ability to easily access every part of your truck bed. These panels are held in pace by gas struts to ensure that they open and close smoothly.
Keeps Your Gear Secure
To provide maximum security for items in your bed, each panel on the DiamondBack HD has a locking handle that requires a key to unlock. Metal rods hold each of the panels in place when closed.
Repels Water
The HD incorporates a water-resistant seal around the edges of the cover to prevent water intrusion. Gutters are located at the center panel to channel water away from the bed when the cover is being opened.
