Profile: Technical Products Co. deals with plug insertion tools, electrical plugs, expansion plugs, rubber plugs, and floor friction test equipment. Our model 80 floor & footwear friction tester is an extremely simple instrument that measures ''slip resistance'' by determining both the static and kinetic co-efficients of friction between leather (dry), and rubber (dry & wet), and the floor surface. The contact area of the leather pads is designed to simulate the pressure caused by a 160 lb. person wearing leather footwear.
