Tin Knocker has introduced the TK S & Drive Plus and the TK Fourplex. The company refers to the products as “Money Making Machines.” According to Tin Knocker, many contractors buy S&Drive cleats and throw away their sheet metal scrap. These S&Drive roll formers from Tin Knocker were developed to quickly and efficiently turn scrap metal into cleats, which means the machines pay for themselves in scrap savings.
