UnderCover UC4146 SE One-piece Truck Bed Tonneau Cover Toyota Tacoma 16-23 6'2"
UnderCover SE
Premium one-piece truck bed cover combining sleek styling, exceptional security, and superior weather protection in a lightweight, durable design.
Durable construction: Molded from premium ABS composite with a textured black finish and aerodynamic style lines. The patented X-Effect X-pattern bracing minimizes side-to-side and corner-to-corner flex whether the cover is open or bearing weight.
Weatherproof and secure: Features an EPDM rubber double-bulb seal system to prevent moisture intrusion and a low-profile, single-point keyed lock for theft resistance. The wrap-around lip further secures the tailgate when the cover is closed.
Convenient operation and lighting: Integrated gas-charged struts assist opening for full bed access, and an integrated LED overhead light illuminates the cargo area for loading and unloading in low light.
