These 3 x 12 x 4-1/2" kraft corrugated bin boxes are constructed from ECT-32-C single-wall corrugated board and fold into shape along pre-scored lines — no tape, staples, or tools required. The one-piece design eliminates assembly hardware while delivering a rigid, self-supporting structure.

The 12-inch depth accommodates standard warehouse shelving units and parts bin systems, making these boxes a practical fit for manufacturing stockrooms, distribution centers, MRO supply rooms, and retail backstock areas. They are especially useful for organizing small components, hardware, and loose parts by SKU or category across multi-bay shelving runs.

The natural kraft finish holds up in industrial environments without showing routine handling wear. Each unit weighs approximately 0.14 lbs, keeping added load on shelving minimal. Boxes are sold in bundles of 50 and ship via parcel carrier.
