Built To Last
The DiamondBack 270 is made out of .080" aluminum diamond plate. This gives it the ability to endure whatever comes its way, whether it's from Mother Nature, or heavy cargo. In fact, it can support up to 400 lbs on top of it which is perfect if you are the working man or if you just enjoy doing outdoor activities. There is an optional black spray-on finish coating available if you want a textured black finish to prevent scratches and match your truck.
Maximum Bed Access
Tired of having to climb into your truck bed just to get your belongings out? The DiamondBack 270 tonneau cover is here to put all that to an end. It features a unique 3-hatch design which means the three large panels can open up and give you full bed access in just seconds. If you ever need more room to haul taller cargo, you can remove the back panel.
Theft Protection
DiamondBack wanted to offer maximum security, so the cover features keyed lock handles on each door that requires a key to open. This ensures that no one will be able to open the cover without having the key. Metal rods are used to lock the panels into place. Without the key, your cargo will be secure from even the most determined crook.
Sealed Against Weather
DiamondBack knows how to keep a truck bed dry. They used a neoprene pressure gasket around the perimeter of the tonneau cover for the most affective defense against the elements. This extremely durable seal comes in contact with the bed rails for 360?? protection. You can rely on the 270 to keep your valuables safe a dry, no need to store things in the cab.

Limited Lifetime Warranty
We build the toughest truck bed covers on the market and we stand behind them. DiamondBack products come with a limited lifetime warranty that covers both the manufacture and parts of the cover. If your DiamondBack needs some help and you're the original owner, please let us know at 1.800.935.4002 or fill out a warranty claim and we'll try to make it right. Chances are it's an easy fix, but if a repair or exchange is needed we'll help you through the best solution step by step. Be sure to have your serial number handy when you call.

We've built the DiamondBack to handle just about anything you can throw at it—literally. We build 'em tough and with you in mind. However, there are always exceptions. Here are a few things this warranty does not cover: exceeding the respective load ratings, misuse, improper installation, damage due to accidents, corrosion, alterations that modify the DiamondBack design and function, and lack of care and maintenance.

Exclusions to this Limited Lifetime Warranty includes factory-applied coatings which are warrantied for 3 years, excluding abrasion, franchise-applied spray-on coating, and ATV Carrier packages.
