The innovative Happijac Frame Mount Tiedown works with your truck and frame to provide unsurpassed safety, strength, value, and truck camper handling peace of mind. Happijac's patented Direct-to-Frame mounting system attaches to the truck frame components from above and works in combination with the Happijac anchor plates, guide plates, stabilizing bar, and the truck bed to create an I-beam truss structure. This unique I-beam structure provides unmatched tiedown performance and security. While other tiedowns may "hold your camper down", only Happijac tiedowns prevent camper movement in all directions (forward-backward, up-down, yaw, pitch, and roll). The complete Happijac Frame Mount Tiedown Systems consists of three key components (FT Tiedown kit, Happijac Turnbuckles, and stabilizing bar). Must purchase each of the components separately.
