The Westin Hard Tri-Fold Tonneau Cover is a hard folding bed cover for trucks. It has a low-profile, flush-mount look and helps protect cargo from weather, road debris and everyday wear.
The panels are reinforced aluminum with UV-resistant construction. The frame and supports are aircraft-grade aluminum alloy with a black powder-coated finish. Waterproof and dustproof seals and an integrated internal drainage system help keep the bed dry.
The cover folds in three sections, giving partial to full bed access and room for larger cargo. A squeeze lever system opens it manually. It installs with a custom-fit clamp system and requires no drilling.
