TruXedo Sentry 2004-2021 GMC Truck Bed Cover

The all-new Sentry by TruXedo combines all the same great features of the Sentry CT but with an industrial-strength, leather-grain vinyl fabric. This hard roll-up style truck bed cover features an Xtra-low profile. We’ve pressure bonded the vinyl fabric to heavy-duty aluminum slats making Sentry the ultimate in durability and security.

When rolled up tightly at the cab, the cover provides full bed access without blocking rear view visibility or the third brake light. When closed, the Sentry’s flush mount profile delivers a sleek look that’s sure to impress! An extra security latch is located towards the center of the cover for enhanced security so you can rest in the fact that your cargo is safe and sound.

  • Industrial - Strength Vinyl Fabric - Installation is quick and easy and does not require the use of special tools or drilling. The Sentry comes backed by a 3 year warranty.
  • Xtra-Low Profile - The Sentry rails are incorporated into the design providing a distinctive flush mount look while enhancing the overall look of your truck.
  • Durability & Security - The vinyl fabric is pressure bonded to heavy-duty matte black aluminum slats for increased durability and security.
  • Quick - Release System - The entire cover can be removed in seconds, without tools, providing true 100% full bed access.
  • Easy to Use - The slam latches at the tailgate allow you to open the cover from either side of the truck. An additional security latch, located towards the center of the truck bed, enhances the security of this cover.
