Construction & Design

The LOMAX Hard Tri-Fold Cover features strong yet lightweight aluminum panels reinforced with extruded aluminum channels to provide rigidity and cargo security without unnecessary bulk.

Flexible rubber seals and reinforced vinyl-coated hinges help reduce vibration while creating a weather-resistant barrier around the truck bed. The cover overlaps the bed rails with a continuous seal designed to help route water away from the cargo area without requiring gutters or external drain tubes.

When closed, the automatic locking system engages at 10 points along the bed, helping keep cargo protected and out of sight. A convenient release cord allows the cover to be opened from either side of the truck.

Installation & Fitment

The B3020089 installs using Access's TIGHT BITE clamp system and does not require drilling into the truck bed. The cover can also be removed and reinstalled when full bed access is required.
