Features
- Heavy Duty Aluminum Plate: ATB builds the A-SU41 from aluminum plate it calls contractor grade, made to withstand road vibration and weather extremes.
- Double Top Hinged Doors: Two diamond tread doors hinge at the top, so you can open one end of the long box at a time or both for full access.
- Gas Spring Assist: Self-powered gas springs lift each door and hold it open while you work.
- Heavy Duty Shelf: A reinforced heavy duty shelf splits the compartment so smaller tools and parts stay off the floor.
- Stainless T-Handle Locks: Stainless steel dolphin tail T-handle locks secure the doors; ATB calls them tamper resistant.
- Rail or Flatbed Mounting: The A-SU41 mounts on a flatbed or on the side rails of your truck and pairs with ATB's DU Series drawer boxes.
Description & Fitment
This ATB A-SU41 is the long, double door version of ATB's aluminum top side mount utility box. Two diamond tread doors hinge at the top and lift on gas springs, a heavy duty reinforced shelf organizes the inside, and stainless steel dolphin tail T-handle locks keep it closed. ATB calls the build contractor grade and makes it in the USA.
Fitment & Compatibility

For a shorter box with one door, see the A-SU41 single door version.
Fits: Flatbeds and truck side rails (measure the rail length; see the size table)
