The DuraLiner gives you 7X the protection of spray on bedliners! Its skid-resistant top helps protect your cargo by reducing cargo movement and not scratching your cargo like a spray on will. A perfect fit if you expect to mount a truck cap or tonneau cover on your truck. The DuraLiner under-rail model also offers the added features of two-tier and compartmental loading. It’s easy to separate your cargo with Penda’s molded-in board holders. Specially designed detents, a Penda exclusive, lock boards into place. Our board holders are custom designed to match your truck. Their strength is supported by the truck bed, so every load is rock-solid. Our vertical boardholders help separate your load for even greater protection. They also offer another option for double-layer loading, so you have maximum versatility. No-Drill installation on your bedliner with a lifetime warranty.
