The Sentry CT 1573316 is the heavy-duty GM version for the 6'9" bed, 2020-2026. It works with or without the MultiPro or Multi-Flex tailgate and is not compatible with the CarbonPro bed.
For security there are patented level-2 locks, a tension cable and as many as six automatic latches.
There is no bulky canister, so more of the bed stays usable. TruXedo describes the Sentry CT as a soft roll-up's cargo space with a hard cover's durability, assembled in South Dakota with a five-year warranty on hard parts and fabric.
The rails are vehicle specific and self-leveling, and the clamp-on design needs no drilling on most trucks. Plan on under an hour.
Latch it fully closed or roll it up and strap it at the cab before driving. Avoid silicone or petroleum conditioners.
