The BSC PREFERRED MTCAP6 is a replacement and supplemental end cap designed for round mailing tubes. These caps seat securely on tube ends to keep contents protected during transit and prevent accidental opening or loss of the cap in shipping. Sold in a case of 100 units, they are a practical stock item for mailrooms, shipping departments, warehouses, and fulfillment operations that use round mailing tubes at volume. The secure fit means tubes can be resealed and reused, reducing material waste without compromising shipment integrity.
These caps are suited for use in any environment that relies on round mailing tubes for shipping rolled documents, posters, blueprints, or similar materials. The case quantity of 100 makes them appropriate for high-throughput shipping operations as well as facilities that want a ready supply of replacement caps on hand. They are compatible with standard round mailing tube designs and provide a consistent, reliable seal across repeat use cycles.
Designed to fit standard round mailing tubes. Equivalent to part number S-7021 as noted in product data.
End caps are installed by hand - no tools required. Press the cap firmly onto the open end of the round mailing tube until fully seated before sealing or shipping. Inspect the cap seating before dispatch to confirm the cap is flush and will not shift under normal handling. Caps should be stored in a dry environment to maintain their fit and form.
