These kraft jumbo mailing tubes measure 5 inches inside diameter and feature .125" thick, 3-ply spiral wound construction. The heavy-wall body delivers rigid, crush-resistant performance that resists bending under load — making these tubes a dependable choice when standard mailing tubes lack the girth or wall strength a shipment demands.

The 5 inch interior diameter accommodates rolled calendars, posters, architectural drawings, large-format banners, fabric rolls, and bundled documents that require extra clearance to prevent compression damage. Print-on-demand operations, architectural firms, trade show suppliers, and retail distributors routinely rely on this diameter for oversized rolled goods.

Listed length reflects usable interior space; actual tube length is slightly longer to accommodate end caps, which are included with every tube. Each case contains 15 tubes. The .125" spiral wound wall thickness is consistent across the full 26 inch length, ensuring uniform protection from end to end.
