Security Chain Company or SCC, began in 1969 as a division of Burns Bros. Inc., headquartered in Portland, Oregon. In addition to offering a complete line of traction products both cable and link style, SCCs product mix expanded to include a wide variety of bulk chain & accessories for industrial and transport applications, cargo/load control products and lifting products.
