Description Overview
Are you looking for maximum security and structural integrity for your truck bed? This Hard Tri-Fold Tonneau Cover is constructed from heavy-duty aircraft-grade aluminum panels, forming a rigid barrier against environmental exposure and theft. Unlike soft covers, the reinforced panel system supports up to 661 lbs. of evenly distributed static weight, helping it maintain structural integrity under heavy snow loads or utility use. Designed for a factory-level fit, the flush-mount profile integrates cleanly with your bed rails to reduce aerodynamic drag while helping prevent moisture intrusion. EPDM rubber seals work alongside an internal drainage system to channel water away from the bed. The manual latching mechanism is positioned behind the tailgate, keeping cargo secure and inaccessible when the tailgate is locked. Constructed from aluminum panels, it installs with a vehicle-specific, no-drill clamp system for a secure, vibration-resistant fit without having to worry about any permanent modifications. PRODUCT SPECIFICATIONS: Color: Black Finish: Powder Coated Material: Aluminum Mounting Type: Under-bedrail aluminum clamp Construction: Aircraft-grade aluminum hinged panels Bed Fit: Flush with bed rails Seal Type: EPDM rubber Latch Type: Manual latch behind locked tailgate, not accessible when tailgate is closed and locked
