The BSC PREFERRED P3018K is a kraft mailing tube designed for document storage and postal shipment. Built with 3-ply spiral wound construction, each tube offers reliable resistance to bending and crushing during transit. White plastic end caps are included and snap securely into place, preventing contents from shifting or caps from dislodging during shipment. Sold in a case of 24 tubes, the P3018K suits high-volume shipping rooms, print shops, architectural firms, and any trade or facility operation that regularly ships rolled documents, blueprints, or drawings.
These tubes are suited for both residential and commercial applications wherever rolled or cylindrical documents need protection. The usable interior dimensions are the listed sizes - actual tube lengths are longer to accommodate the snap-in end caps, which add approximately 3 inches per cap to overall length. The tubes are reusable after initial shipment and are recyclable at end of life, making them a practical choice for facilities managing document logistics on a recurring basis.
Designed as a direct equivalent to part number S-2642. Suitable for standard mailing tube applications involving rolled documents, blueprints, drawings, and similar materials.
Insert rolled documents into the tube before snapping end caps into place. No tools are required for assembly. Ensure contents do not exceed the stated usable length to allow caps to seat fully and securely. Tubes should be addressed and sealed per carrier requirements before shipment.
