Construction & Design

The LOMAX Hard Tri-Fold Cover features strong, lightweight aluminum panels reinforced with extruded aluminum channels for added rigidity and security. Flexible rubber seals and reinforced hinges help reduce vibration while creating a weather-resistant barrier around the truck bed.

When the cover is closed, its automatic locking system engages multiple locking points along the bed to help keep cargo protected. An integrated pull cord releases the locks for quick access when the cover needs to be opened.

The low-profile design sits less than approximately 1/2 inch above the bed rails, providing a clean appearance without the bulky look of many traditional hard folding covers.

Installation & Fitment

The B3020099 uses the TIGHT BITE clamp mounting system for straightforward installation without drilling into the truck bed. The cover can also be removed and reinstalled when additional bed access is required.
