Our Covers
All Advance Covers leave the factory with a four point slam latch system. The latches are located on both sides in the front and rear. This design gives the Advance Cover the capability of opening up from the front or rear. There are also two locks in the front and rear to keep your cargo safe and secure. Our Covers are water resistant which is credited to the seal design and placement.

About Advance Cover
The first Advance Cover was designed by John Kooiker. John, along with his wife Shirley and other family members have constantly strived to make Advance Cover the most convenient, toughest, and securable hard panel folding Tonneau cover on the market. Advance Cover Corporation LLC began business in January 1998, in Grand Rapids Michigan. The shop grew and sales increased which caused Advance Cover to move to Caledonia, Michigan in 2002. With a bigger warehouse and production area Advance Cover could now meet its customer’s expatiations.

Easy Installation
Installing the G3 Supra cover is fast and undemanding task thanks to the new rails. All you have to do is clamp the rail on the inside of each side rail on your truck bed. The measurements are done at the factory. On some models measuring our D-seal set back is required. After the rails are installed all that has to be done is attach the G3 Supra Cover.
