Features to know about

Streamlined Security: Tri-Fold Hard Design

Keeping your gear safe doesn’t have to mean wrestling with a bulky cover. This hard tri-fold tonneau uses fiberglass reinforced plastic panels that latch securely at the tailgate. When the tailgate is locked, the bed stays locked too. The panels fold quickly for partial access, and you can remove them completely without tools when you need the full bed open.

Tough Yet Lightweight: Fiberglass Reinforced Plastic Construction

Unlike heavier aluminum covers, this one uses fiberglass reinforced plastic for a high strength-to-weight ratio. It’s rigid enough to support up to 400 lbs of evenly distributed weight but still light enough to lift easily. The FRP material shrugs off scratches and absorbs impacts, so it keeps looking sharp even with everyday use.

Weather Protection Without Drain Tubes: Sealed Hinges and Arched Panels

Rain, dust, and debris stay out thanks to rubber perimeter seals and reinforced, vinyl-coated panel hinges. The slight arc in the cover helps water roll off instead of pooling, eliminating the need for drain tubes. Whether you’re driving through a downpour or kicking up dust on back roads, your cargo stays clean and dry.

Clean Look and Rack Friendly: Low-Profile Mounting

The cover sits about 1/2" above the bed rails for a tight, flush fit that doesn’t spoil the truck’s lines. Because the side rails leave stake pockets open, you can still mount racks or tie-downs without interference. The simple black finish has a deep color that resists fading and blends in with the truck’s natural look.

Quick Setup, No Tools Needed: Simple Clamp-On Installation

Getting started is straightforward with no drilling required. The durable side rails clamp on securely, supporting the panels without complicated adjustments. Once in place, the integrated storage clips with retractable straps keep the folded sections steady while you drive, so you get easy operation and reliable protection every time.
