These 5 x 5 x 48 inch kraft square mailing tubes are built from ECT-32-B single-wall corrugated board, giving long, rigid items structured sidewall protection without the bulk of round tube alternatives. The square cross-section is the defining advantage here — it prevents rolling during packing, conveying, and transit in a way round profiles cannot match.

The no-tape, no-glue fold-together construction makes these tubes practical at high-volume packing stations where assembly speed matters. They ship and store flat, reducing the space burden when tube inventory is staged in a warehouse, and the one-piece format eliminates the need for separate end caps in most applications. Industries including framing, printing, architectural drafting, apparel, and industrial parts distribution rely on this format for posters, drawings, rods, and similarly elongated goods.

Each tube measures 5 x 5 inches in interior cross-section and 48 inches in usable interior length. Tubes are sold in bundles of 25 and ship via parcel carrier.
