These 8 inch inside diameter kraft jumbo mailing tubes feature a .125" thick, 3-ply spiral wound wall that delivers rigid resistance to bending, crushing, and compression — making them a dependable choice where standard mailing tubes fall short in diameter or structural strength.

The large bore and extended 36 inch usable interior length make these tubes well suited for architectural blueprints, wide-format prints, banners, fabric rolls, canvas artwork, and industrial components such as rods, mandrels, or shaft stock. Print shops, engineering firms, trade show suppliers, and industrial distributors are common users.

Each tube ships with end caps included; additional 8" replacement end caps are sold separately for high-volume operations. Cases contain 10 tubes at approximately 32.8 lbs per case. Note that the listed 36 inch length reflects usable interior space — the actual tube is slightly longer to accommodate the end caps.
