48 x 12 x 12" Double Wall Boxes

These 48 x 12 x 12 inch double wall corrugated boxes are built for shipments that demand greater structural integrity than standard single wall cartons. Constructed from ECT-48 double wall kraft corrugated board, the dual-layer configuration delivers enhanced puncture resistance, compression strength, and stacking durability that single wall cartons cannot match.

The 48 inch interior length makes these boxes a reliable fit for rods, tubes, rails, lumber, textiles on cores, fluorescent bulbs, and similar elongated goods. Manufacturing facilities, building materials distributors, e-commerce fulfillment centers, and industrial supply operations regularly rely on this format where standard cubic box proportions fall short.

Each box weighs approximately 3.56 lbs, reflecting the added material of the double wall construction. Boxes ship flat in bundles of 10, reducing storage footprint in receiving areas and keeping replenishment simple. Ships via parcel.
