6 x 48" Kraft Jumbo Tubes

These 6-inch inside diameter kraft jumbo mailing tubes feature .125-inch thick, 3-ply spiral wound kraft board construction — a wall thickness that delivers rigid resistance to bending, crushing, and compression through the full shipping and handling cycle. The listed 48-inch length reflects usable interior capacity; actual tube length extends slightly beyond that dimension to accommodate end cap fitting. End caps are included with each tube.

The 6-inch bore and 48-inch usable length make these tubes well suited for architectural and engineering drawings, large-format print and signage, textile and fabric rolls, and industrial components too long for standard mailing tubes. Print shops, sign distributors, architectural firms, and manufacturers rely on this format for both outbound shipping and on-site rolled-goods storage.

Wall construction uses three plies of spiral wound kraft board for consistent roundness and uniform wall integrity along the full tube length. Cases contain 10 tubes and weigh approximately 32 pounds — bulk handling equipment is recommended when receiving full-case quantities.
