These 6 inch inside diameter kraft mailing tubes are built for oversized rolled contents that standard tubes cannot accommodate. The .125" thick, 3-ply spiral wound kraft wall delivers rigid resistance to bending, crushing, and compression — maintaining tube shape under the load and handling stresses of outbound shipping.

The 30 inch usable interior makes these tubes a practical choice for architects, engineers, and print shops shipping blueprints, technical drawings, and large-format prints, as well as retailers and e-commerce operations dispatching rolled banners, posters, and canvas artwork. The rigid construction also supports long-term document archiving and storage in warehousing environments.

Each tube is supplied with end caps installed; the actual tube length is slightly longer than 30 inches to accommodate end cap fitment. Compatible 6" end caps are also available separately for replacement or multi-use needs. Cases contain 10 tubes.
