How to Install UnderCover Triad Tonneau Cover


UnderCover, Inc. warrants the structure of your cover to be structurally free from defects in material and workmanship for (3) three years from the retail date of purchase. The hinges, seals, and hardware are warranted to be free from defects in material and workmanship for (3) three years from the retail date of purchase. This warranty applies only to the original purchaser and is nontransferable. Your original sales receipt will serve as proof of purchase for this warranty. Before credit can be issued on a warranty claim, proof of defect may be required. This can be determined at the time of the claim.

Not covered under this warranty is failure due to neglect, improper installation including any modifications to installation hardware, alterations, addition of equipment, abuse, accident, weather related damage, exposure to chemicals that are not labeled "safe for rubber" and normal wear from lack of maintenance.

Always read the ingredients of any product you are using to clean your cover. Make sure that you use only products that are safe for use with rubber. Many chemicals contain material that will permanently discolor or damage your cover hinges and seals. This is not considered a manufacturer defect.

Incidental or consequential damage or loss of contents due to use, neglect, lack of maintenance, misuse or abuse of the cover is the sole responsibility of the truck owner and operator. Paint damage to your truck is not covered under this warranty. When operating your truck always keep the cover in either the fully closed and latched position, or one of the two approved open positions. The first approved open position would be the first, second, and third panel stacked onto the forth panel and the buckles must be secured together. The second approved open position would be all four panels standing up vertically behind the cab. In this position both prop rods must be attached and the buckles secured. Do not operate the truck at excessive speeds with the cover in either open position.

In the event that your cover is found to be defective under the terms of this warranty, it is at the discretion of UnderCover, Inc. to repair or replace the defective part. All repairs must be made under the direction of UnderCover Inc. UnderCover Inc. is not responsible for any transportation costs associated with the warranted claim.

The panels of your cover require only periodic cleaning with mild car wash soap. Avoid use of all abrasive type cleaners as they may dull the finish. Some chemicals and fluids such as insect repellents, oils, solvents, and lubricants could potentially damage the rubber hinges and seals and void the warranty.
