The BSC PREFERRED P3038K is a kraft mailing tube designed for document storage and postal shipment. Built with 3-ply spiral wound construction, each tube provides the rigidity needed to protect rolled documents, blueprints, posters, and similar materials in transit or on the shelf. White snap-in end caps are included and are engineered to stay seated during shipment without additional fasteners. Tubes are sold in a case of 24 units. Dimensions listed by the manufacturer reflect usable interior space; actual tube length is longer due to the additional 3 inches added by the end caps when installed.
These mailing tubes are suited for mailrooms, print shops, architectural firms, and any facility that regularly ships or stores rolled documents. The 3-ply kraft construction balances economy with structural integrity, making them appropriate for both single-use mailing and repeated storage cycles. Because the tubes are reusable and recyclable, they are a practical choice for operations managing high document volume. This SKU ships as a case of 24, consistent with a unit of measure designated as CS.
The P3038K is equivalent to part number S-12046. These tubes are suitable as a general-purpose mailing and storage solution for rolled documents and are compatible with standard postal and courier shipment workflows.
No tools are required for assembly. Insert rolled documents into the tube and press each white end cap firmly into place until seated. Verify caps are fully engaged before handing off for shipment to prevent contents from shifting. Tubes should be stored horizontally or vertically in a dry environment to maintain structural integrity.
