Built Heavy Where It Counts

• .100" thick diamond tread aluminum construction for serious strength without unnecessary weight
• .125" thick smooth aluminum bottom corner reinforcement for added durability in high-stress areas
• Full wrap, one-piece body design for structural integrity and long-term performance
• Welded gussets in each corner of the door frame to prevent sag and frame flex

This is professional-grade construction designed for real jobsite abuse — not light-duty storage.

Secure and Built to Last

• Strattec high-quality key cylinder for dependable locking performance
• Free-turning handle when locked to help resist forced entry
• Three-point latches standard on 36 in, 48 in and 60 in models for added security
• Full HS aluminum lock cover protection
• Stainless steel bolted hinge for long-term reliability

Weather-Ready Design

• Genuine Trim-Lok bulb seal to help keep out water, dust and road grime
• Overhead rain gutter to channel moisture away from the door opening

Your tools stay protected — even when the weather doesn’t cooperate.

Fit It to Your Build

• Available in multiple sizes to match your chassis and storage needs
• Door style options: drop-down door, swing door or barn door
• Finish options: standard aluminum or textured matte black
