Construction & Design

The LOMAX Hard Tri-Fold Cover features aluminum panels reinforced with extruded aluminum channels, creating a rigid structure while keeping the cover lightweight and easy to operate. Flexible rubber seals and durable hinges help reduce vibration and provide protection against rain, snow, dirt, and other elements.

When closed, the automatic locking system engages multiple locking points along the bed for added cargo security. An integrated release system allows the cover to be opened quickly when access to the truck bed is needed.

The water-shedding design helps direct moisture away from the bed without requiring bulky external drain tubes, while the low-profile construction maintains a clean, factory-style appearance.

Installation & Fitment

The B3020109 uses a clamp-on mounting system for straightforward installation without drilling into the truck bed. The cover can also be removed and reinstalled when maximum bed space is required.
