Welded Corners Eliminate Leak Points

Welded Corners Eliminate Leak Points

A failed weld on a toolbox doesn't just mean lost tools — it means water intrusion that corrodes your equipment and your truck bed. The ATB Top Mount Compartment Toolbox is fully seam welded on all seams and corners, eliminating the gap-prone spot welds that plague big-box store units. This engineered design uses stainless steel continuous hinges running the full lid length, paired with an adjustable lock striker and automotive bulb weather sealing. The result is a compartment toolbox that respects your investment by keeping what's inside dry and secure, regardless of road conditions or weather exposure.

Reinforced Lid Stays Open Without Struggling

Reinforced Lid Stays Open Without Struggling

The channel braced reinforced lid with gas springs means you're not fighting a heavy steel or aluminum lid while trying to grab tools one-handed. The lockable stainless steel lift handle latch gives you controlled access, and the gas spring mechanism holds the lid securely open at any angle. Inside, galvanized 18-gauge hemmed adjustable dividers let you organize compartments around your actual tool set rather than accepting a fixed layout. A rubber floor mat prevents tools from sliding and scratching the powder-coated interior. This is craftsmanship aimed at daily use, not occasional access.

Seven Lengths Match Any Truck or Flatbed

Seven Lengths Match Any Truck or Flatbed

Available in 48, 60, 72, 82, 84, 90, and 96 inch lengths — all with a consistent 14 by 6 inch profile — the ATB Top Mount Compartment Toolbox fits standard truck beds, trailer frames, and flatbed installations without modification. Choose between .09 inch smooth or .10 inch tread plate aluminum for weight savings, or 14 gauge steel when maximum rigidity is the priority. The zinc epoxy primer with MR powder baked topcoat finish provides lasting corrosion resistance in environments where road salt, moisture, and UV exposure are constant threats. Every unit ships free with a complete mounting kit.

“Mounted a 72-inch aluminum model on three of our service trucks. The seam welding is noticeably better than the units we replaced — no water inside after two months of rain and highway driving. Dividers actually adjust without bending. This is the kind of toolbox you buy once.”
