A three-part rolling tool chest that stacks a top box, a heightening cabinet and a bottom cabinet into one 52-in tower, so tools are sorted by size across separate compartments instead of piling into a single deep bin. The heightening cabinet is the piece that changes how the chest works day to day: it lifts the top box to a height where tools come to hand without stooping, and it adds its own storage between the two cabinets. The top box measures 20-in by 10-in by 13.5-in and detaches completely, and because it locks it can be carried to the work and left there without the contents spilling or walking off. Underneath, the bottom cabinet is 23.5-in by 13-in by 26-in, and the whole tower stands 23.5-in by 13-in by 52-in overall. All six drawers run on ball-bearing slides so they open smoothly under load and close without fighting, and each is rated for 22 lbs against a 200-lb capacity overall. A protective liner sits inside to keep tools from scratching against bare steel or picking up corrosion. The body is cold-rolled steel with a frosted surface that reads as metal rather than paint. Four universal casters move the 60.5-lb chest and 2 of them lock, a single-sided handle steers it, and removable side hooks hang the tools that are reached for most.
