This Sentry CT is cut for the long bed on the 2007-2021 Toyota Tundra, the 8'2" box (97.6"), on trucks without the deck rail system. Under the RTxTechWeave canvas is a row of interlocking aluminum slats, which makes it a hard roll-up you can still roll right up to the cab. Fitting it is a clamp-on job that needs no drilling on most trucks. 400 lb is the rating, with the weight spread evenly across the closed slats. Where the tailgate has a key lock, the latches stay out of reach until it is unlocked and opened. You get TruXedo's five-year warranty with it.
