The original Access tonneau has premium features at an economical price. This truck bed cover rolls up so that you can haul bulky items and rolls down to shield and secure your vehicle's bed and cargo. The custom-fit tonneau sits 1-1/2" above your truck bed and keeps air from getting caught by the tailgate, thus reducing drag. That can improve your gas mileage by up to 10 percent. And the exclusive Access Slantback fit angles toward your tailgate to give your truck a stylish, streamlined look.

Rolled Access Original tonneau cover with straps

Velcro closures on the sides help seal the cover to your truck box and allow you to peel it back quickly for easy access. The tonneau stores neatly behind your cab, secured by premium storage straps that are designed to keep the cover from rubbing against the cab.

The cover fabric is reinforced polyester mesh coated with UV-blocking vinyl, so it won't fade in the hot sun. The material stays flexible down to -40 F and won't shrink, regardless of the temperature. Black powder coated aluminum bows line the underside of the tonneau and act as ribbing that supports the cover and makes it easy to roll up.

XT Dial tension adjuster for Access Original tonneauElement seal behind cab for Access Original tonneau

Customize the cover tension by turning the XT-Dial easy-grip tension adjuster at the front of the cover, near your cab. The Element weather seal at the cab end and a reinforced vinyl flap at the tailgate help to keep out dirt, rain, snow, and ice.

Tite Bite clamp for Access Original tonneau cover

The contoured, black powder coated aluminum tonneau rails resist rust. They sit inside your truck bed side rails so that you can still use stake-pocket-mounted accessories, such as a ladder rack or tie-down anchors. Easily install the rails on a truck with an under-the-rail, drop-in bed liner. Over-the-rail liners can be cut to allow room for the installation clamps. The tonneau's rails attach easily to your truck bed side rails using Tight Bite clamps. The specially designed teeth on these clamps seize the integrated ridges in the rails, ensuring a firm grip.

Auto Latch II for Access Original tonneau cover

Once the tonneau cover is unrolled and in place, the AutoLatch II dual locking system automatically engages 2 locks - 1 on each side - to hold the tonneau closed. And locking the cover won't interfere with your tailgate - open and close it as usual or add a tailgate lock (sold separately) to get secure storage for your cargo. To unlatch the cover, simply pull the cord for easy, one-hand operation. Cover your assets with this tonneau from Access.

Review from a similar Access Original in Tonneau Covers

OVER ALL VERY GOOD This is a nice cover. It is a changle to install. It took me a little over 2 hours to put in by my self. The problem is with the Ridgeline, NOT the cover. You must take all the bed walls off the truck and this takes time. There is drilling involved, but measure twice and drill once. I marked where the holes were going to go and put the wall back in the truck to make sure it was in the correct spot. The directions were fair, you just have to take your time and double check everything. I am sure if you have the correct tools you could do this job. It is well worth the time because it looks great when you are all done. 1686

Review from a similar Access Original in Tonneau Covers

Roll-up cover installed easily. After 1 year outdoor exposure it still provides good weather protection for the bed. The cover material is taut, does not flap and the hook and loop material seals the sides well. 337525

Review from a similar Access Original in Tonneau Covers

Installed much easier than expected, operation is convenient and easy, and my truck gained 1 mpg. Also purchased the tailgate seal and it made it surprisingly dust and weather tight. 141324
