The BSC PREFERRED 4450 is a tall corrugated box designed for end-loading applications, making insertion and sealing fast and straightforward. Built from 200/ECT-32 kraft corrugated material, these boxes deliver solid structural integrity for items that are too long or awkward for standard cartons. They are a direct alternative to mailing tubes, offering a flat, rigid enclosure that protects contents during transit and storage. Each box ships flat, so storage footprint before use stays minimal. These boxes are sold in packs of 25 and are well suited for shipping, warehousing, and distribution operations where high-volume packaging is routine.
This product fits packaging and shipping workflows that handle elongated or cylindrical items such as posters, documents, rods, tubing samples, or similar goods. The end-loading design allows contents to slide in from either end without forcing items through a top opening, reducing handling time on a packing line. Sold and shipped flat in bundle quantities, the 4450 is practical for facilities that need to keep packaging stock organized and space-efficient.
Designed as a general-purpose end-loading corrugated box suitable for packaging elongated or tube-shaped items in shipping and warehousing applications. This product is equivalent to part number S-21584.
No tools or trade licensing are required to use these boxes. Ensure contents are properly cushioned or wrapped before insertion to prevent movement during transit. Seal both ends completely with pressure-sensitive or reinforced tape rated for the intended shipping method. Follow carrier guidelines for maximum weight and dimensional limits when loading and labeling each carton.
