4 x 4 x 36" Tall Corrugated Boxes

These 4 x 4 x 36 inch tall corrugated boxes are built from ECT-32 single wall kraft corrugated board, delivering reliable column strength and puncture resistance in a narrow, end-loading format. The square interior footprint and 36 inches of interior height make this box a flat-packed, stackable alternative to mailing tubes for products that require a rigid enclosure.

The end-loading configuration suits long, slender items such as curtain rods, fishing rods, architectural samples, rolled artwork in rigid sleeves, fluorescent bulbs, and similar products. E-commerce fulfillment centers, lighting distributors, sporting goods suppliers, and manufacturing operations commonly use this format when tube packaging is impractical or when a square cross-section better matches the product geometry.

Boxes arrive flat-packed in bundles of 25, reducing storage footprint until they are needed on the packing line. Constructed to ECT-32 single wall standards, each box supports standard small-parcel outbound shipments. Order in single or multiple bundles to align with fulfillment volume.
