The DuBose Strapping 12178 (or DUB12178) is a box of 5/8-inch serrated strapping seals designed for secure industrial packaging. Manufactured by DuBose Strapping, these heavy-duty steel seals feature an internal serrated (gripped) pattern engineered specifically to bite into plastic, poly, or polyester strapping. This prevents structural slipping under high tension during shipping and material handling.
