Built Tough
The DiamondBack SE hard tonneau cover is constructed out of .08" aluminum alloy, making it one of the strongest truck bed covers on the market. Because of the durable materials used to create this cover, it cannot be ripped or torn and it will easily hold up to anything that gets thrown its way. The cover can be sprayed with an optional black spray-on finish coating for durable, black textured finish to help prevent scratches.
Front And Rear Bed Access
Unlike many other bed covers that only offer 3/4 bed access, the DiamondBack SE can open from the front or the back, allowing you to have full bed access in a matter of seconds. If you need more room to haul taller cargo, each panel can be removed individually just by sliding it off of the hinge. Optional storage bins from Diamonback offer convenient cargo management.
Theft Protection
If you're looking for a cover that offers maximum security, you'll be happy to know that your search has come to an end. Not only does this tonneau seal over the bed rails, but it can also be locked with a key. Each panel has locking rods that slide directly under the bed rails to help keep intruders out. The SE is easy to open and close with a twist latch that provides dead-bolt security.
Sealed Against Weather
Keeping your belongings dry is as important a keeping them away from thieves. Water can ruin cargo so the Diamondback SE has a neoprene compression gasket to keep the water out. With the tonneau cover closed, it seals around the perimeter of the truck bed. Also, gutters along the middle panel channel water away from the bed when you open the cover.

The Diamondback SE tonneau cover is a worthy investment for your truck. With it being made of aluminum diamond plate, it is far more durable than a fiberglass or vinyl cover. The Diamondback SE is constructed from .080" 3003 alloy aluminum, and has two panels for bed access. As far as security is concerned, there are die- cast zinc lock handles (3/8" deadbolt style steel lock rods) on both the front and rear panel. Diamondback uses flat head machine screws with nylon lock- nuts makes it very difficult to tamper with the hinges. The EPDM neoprene compression gasket runs along the perimeter to protect the items under your cover dry regardless of the weather. At the hinge point there are gutters for drainage. The exterior hardware is made of stainless steel, and additional tie down cleats are sold separately (comes with four tie down cleats). This cover comes with everything needed for installation, and installation should take less that an hour.

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.
