What's the warranty on a DiamondBack truck bed cover?

Three years. Please see our warranty page for more details.

How hard is it to install a DiamondBack?

Not hard. You'll need to know how to use a hex key, a socket wrench, and in some cases, a drill. It also helps to have a second person present. Please have a look at our owners guides for more details.

How are DiamondBack covers mounted to the truck bed?

With truck cap clamps. To mount HDs, SEs, and LTs, one clamp is placed under each corner of the center, stationary panel. To mount 180s and 270s, at least one clamp is placed at each of of he stationary T-members. The access panels on all covers are then attached to the stationary panels using slide-on hinges. Each access panel has lock rods that hold it down when closed. Our owners guides can give you more detail.

Does the cover come with all its weatherstrip already on?

Yes, with one exception. In addition to the the neoprene gasket that's pre-affixed around the perimeter of your DiamondBack truck bed cover, most late-model pickups will need a single piece of weatherstrip stuck to the top of the cargo box bulkhead before the DiamondBack goes on. We provide that strip coiled up in a small, plastic bag that's included in the same box as your clamps and gas springs.

How easy is it to remove a DiamondBack?

Easy. Have a look at our Removable video for more info.

How heavy are DiamondBack truck bed covers?

That depends on which cover. Please visit our "Compare" page. The third row from the bottom in the table there has the weights for all five DiamondBack covers.

Will a DiamondBack work with my fifth-wheel trailer?

Yes and no. You won’t be able to have the cover on and access your fifth-wheel hitch at the same time. However, DiamondBack tonneau covers are made to be taken on and off easily when needed. Many customers with fifth-wheels remove their DiamondBacks and either place them in the trailer or in their cargo beds next to the hitch during travel. They re-install their DiamondBack (10 mins. max) after arriving at their destination.

Does DiamondBack make a tonneau cover to fit behind my crossover tool box?

Yes. You can get a DiamondBack HD, DiamondBack SE, DiamondBack 270, or DiamondBack 180 that fits behind your tool box.

I just got a new truck. Can I use my old DiamondBack cover on it?

Maybe. But probably not. Every DiamondBack tonneau cover is model-specific. If your new truck has the same body style as your old truck (e.g., a 2012 F-250 short box and a 2008 F-250 short box), your cover will fit great. But if your new truck is a different make or body style, the best you'll get—and this is only with some truck pairings—is a serviceable fit. In most cases, and certainly if your new truck's cargo box is a different length, it's time for a new DiamondBack!

Do you make a cover for the Honda Ridgeline or Chevy Avalanche?

No. Those trucks' bed rails do not provide clearance for a tonneau cover that sits on top of the bed rails like a DiamondBack does.

Are DiamondBack covers clear-coated?

No. Clear coating often yellows over time and ends up looking horrible. In addition, scratching clear coat results in a magnified scratch that reflects off the mirror finish of the diamond plate and looks worse. You can buff out scratches in aluminum, but not in clear coat.

Is it possible to keep my DiamondBack shiny?

Yes. Since a DiamondBack truck bed cover is made of polished diamond plate aluminum and isn't clear-coated, you can use an aluminum polish to preserve its shine. We prefer Flitz, but any automotive aluminum polish will do. Typically, once or twice a year will do. If you live in a saltier or harsher-weather region, you might have to polish more often.

Do you spray the black LINE-X or do you have someone else do it?

We do it in house!

I lost my DiamondBack Owners Guide. Can you send me another one?

Yes. In fact, you can go to the Owners Guide page where you’ll be able to download the Owners Guide for your DiamondBack truck bed cover or accessory immediately.
