The BSC PREFERRED SE1027BL is a fixed-length, all-plastic security seal designed to secure trailer doors and transportation equipment. Built from weather-resistant HDPE, this one-piece seal withstands extreme cold and heat without becoming brittle or failing in the field. The patented acetal locking chamber delivers superior tamper resistance, making unauthorized removal or tampering immediately visible. Each seal is consecutively numbered for chain-of-custody tracking and record-keeping. Seals are produced in strips of 20 with no plastic waste, simplifying handling during high-volume sealing operations. This case contains 100 seals.
The SE1027BL is used across freight, logistics, and transportation applications where tamper-evident closure of trailer doors, container latches, and similar equipment is required. It is suited for use by fleet operators, shipping and receiving departments, and logistics professionals who need a reliable, single-use seal that meets standard trailer security requirements. The all-plastic construction makes it lightweight and easy to apply without tools. This product is equivalent to part number H-543BLU.
Designed for use on trailer doors, container latches, and general transportation equipment requiring tamper-evident fixed-length plastic security seals. Equivalent to part number H-543BLU.
No tools are required to apply this seal - insert the strap into the locking chamber until it clicks and cannot be withdrawn. Verify the consecutive number is recorded before sealing. Once locked, the seal must be cut to remove; do not attempt to reuse. Inspect the locking chamber for visible tamper evidence before logging receipt of a sealed shipment.
