Crescent JOBOX Steel Underbed Box 36in x 18in x 18in Black

Description

OSHA-compliant cargo transport demands drop-forged security beneath flatbed platforms, and the Crescent JOBOX Steel Underbed Truck Box delivers heavy steel containment. It mounts below truck decks to store heavy chains and binders. It requires fabricated steel brackets for frame attachment. The rotating T-handle latch draws the door tight against road grit.

Heavy 14-gauge industrial carbon steel forms the box body, side walls, and reinforced door frame. An industrial black powder coat prevents rust from constant road spray, gravel impacts, and deicing salts. Dual steel door cables support the drop-down door. The empty underbed box weighs 74 lbs, measuring 36 inches long, 18 inches deep, and 18 inches high.

Key Features of Crescent JOBOX 792982

Heavy haul truckers buy Crescent JOBOX 792982 units to secure transport chains and ratcheting load binders. Commercial steel underbed box pricing delivers unbeatable durability against constant road gravel blast.

• Heavy 14-gauge steel plate construction stops flying gravel from denting or puncturing walls.
• Drop-down door drops to ninety degrees to allow direct access to heavy steel rigging chains.
• Die-cast stainless steel T-handle latch draws the door tight against internal weather seals.
• Thick automotive bulb gasket seals out road spray, deicing slush, and dirt clouds during highway runs.
• Black industrial powder coat protects the steel against caustic road chemicals and fuel spills.
• Full-length continuous piano hinge distributes heavy door weight along the bottom housing seam.
• Aircraft-grade door support cables hold heavy equipment loads resting on the open drop-front door.

Static Weight Hinge Stress Limits

Laboratory load testing reveals the open door and support cables hold 225 lbs without cable eyelet stretching. The 14-gauge steel tub maintains structural squareness under 350 lbs of internal steel chain load. Door gaskets compress 0.055 inches under latch lockup to pass pressurized road water spray tests. Salt spray tests confirm 600 hours of corrosion resistance around welded hinge tabs.

Underbody Clearance Mounting Realities

Mounting this 74-lb steel box requires two technicians and fabricated steel bracket kits bolted to vehicle frame rails. Do not buy this underbed unit without verifying 19 inches of vertical clearance below flatbed side rails. Keep box walls six inches away from exhaust pipes to prevent heat damage to door gaskets. Drill mounting holes through structural flanges.

• Grease the stainless steel piano hinge leaves twice each year to clear road grit and stop rust.
• Apply water-resistant chassis grease to internal T-handle lock cams every four months.
• Check underbody bracket mounting bolts for tightness after operating across rough construction jobsites.
