Buyers Products Company 18x18x36 Inch Pro Series Black Steel Underbody Truck Box

Description

Slushy winter highway grime and corrosive road salt bombard truck chassis boxes on long hauls. Mount the Buyers Products Pro Series Underbody Truck Box beneath your trailer frame to shield towing chains and hydraulic jacks from road deicers. The drop-down door provides a flat staging surface. Installers must source heavy underbed bracket arms rated for chassis mounting.

Formed from heavy 12-gauge industrial carbon steel, this Pro Series box resists brutal tire gravel blasts. A gloss black powder coat seals all welded seams to block corrosion from magnesium chloride brine. Outer dimensions measure 36 inches long, 18 inches deep, and 18 inches high with an unboxed weight of 82 lbs. Die-cast stainless steel compression latches pull the drop door tight against automotive bulb seals to stop water penetration.

Underbody Deflection Latch Stress Metrics

Drop-door static load testing verifies the twin aircraft support cables hold 250 lbs of dead weight with zero permanent cable elongation. The 12-gauge steel box floor handles 350 lbs of heavy rigging chains with under 0.050 inches downward deflection. Latch compression tests confirm thirty pounds of force pulls the bulb seal forty percent shut. High-pressure wash testing at seventy psi proves zero liquid penetration past the door gasket channels. Continuous piano hinges endure 10,000 cycles without pin distortion or joint binding on test stands.

Chassis Rigging Limits Routine Care

Mounting under trailer frames exposes this steel enclosure to brutal gravel throw and high curb strikes during tight turns. The flush compression latch shields lock tumblers from direct mud spray off truck tires. Do not mount this 82-lb steel underbed box without dedicated structural steel bracket arms rated for 500 lbs minimum dynamic cargo capacity.

• Grease door latch pivots with lithium grease each quarter.
• Inspect cable crimps for fraying after heavy chain hauling.
• Touch up rock paint chips with black enamel to halt frame rust.
