Upgrade your truck with the Westin hard tri-fold tonneau cover, built for strength, security, and a clean flush-mount appearance. Designed specifically for the 66.7-inch bed Toyota Tundra, this cover uses reinforced aluminum panels and an aircraft-grade aluminum frame to protect your cargo from weather, theft, and jobsite abuse.
