UnderCover TR16002 Triad Hard Folding Tonneau Cover Chevrolet Colorado/GMC Canyon 15-22 5'2"
UnderCover Triad
The UnderCover Triad is a premium hard-folding tonneau cover combining lightweight aluminum panels with a sleek matte-black finish for durable, low-profile protection. Its tri-fold design provides easy operation while supporting heavy loads and resisting UV exposure.
The cover is engineered for weather resistance and security: integrated EPDM perimeter and corner seals plus dual hinge seals help keep moisture and debris out, and the aluminum construction delivers strength without excessive weight.
Access and use are straightforward—tailgate clamps release for folding the cover toward the bulkhead and securing with integrated straps to allow partial bed access when needed.
