G.W.B. Rope & Twine, which was one of the foremost North American producers of braided rope from 1973 to 1985, was also the inventor of the automotive grocery or cargo restraint net. The net was introduced with the launch of the Ford Taurus at Christmas 1985, and shortly thereafter the company was sold and became Polytech Netting Industries, which employed several hundred people until moving to Mexico in 1996–97. G.W.B. Rope and Twine's founders, Gordon W. Brown and family, launched G&B Ropes in 1990. (Their son Sean Brown worked with G&B Ropes until it transferred ownership around 1998. Sean Brown then assisted in the development of Orillia's newest rope-making business, Redpoint Ropes.)
