3 x 56" Kraft Heavy-Duty Tubes with Caps

These 3-inch inside diameter kraft mailing tubes measure 56 inches in usable interior length and are built to a .125-inch, 3-ply spiral wound wall specification. That construction delivers rigid, crush- and bend-resistant performance that standard single-ply tubes cannot match, making them the right choice when long, fragile rolled items need dependable protection in transit.

Architects, engineers, print shops, fabric suppliers, and fulfillment operations rely on these tubes for blueprints, technical drawings, large-format posters, rolled textiles, and similar elongated materials. The 3-inch interior diameter accommodates tightly or loosely rolled content without forcing items into a constrictive fit.

Each tube ships complete with end caps included. The listed 56-inch length reflects usable interior space — the actual tube is slightly longer to accommodate cap fitment. Additional 3-inch end caps are sold separately if replacements are needed. Sold by the case of 24 tubes at a case weight of 39.6 lbs. Ships via parcel.
