Product Description:

The Ace Manufacturing HR21 series headache rack for semi truck applications is a premium aluminum cab guard designed to add functional storage while maintaining full rear cab protection. What sets the HR21 series apart from other Ace Manufacturing headache racks is the single full width tray that spans the entire length of the rack, combined with integrated tire chain holders for organized, easy access storage.

Built with a full 5 foot tall aluminum backboard, the HR21 series delivers enhanced cab protection compared to shorter rack designs. Multiple configurations are available to accommodate different visibility and lighting needs, including solid panel versions, jailbar window options, and integrated rear lighting layouts. All HR21 racks are constructed from corrosion-resistant aluminum checker plate and require a compatible mounting kit for proper installation.
