GRIPMASTERS CTS-4 (1 inch) – ALL TERRAIN TRACTION FOR OFF-ROAD VEHICLES Gripmasters are built to provide positive traction for vehicles in icy or rocky conditions where the terrain is uneven or rough. The heads protrude 5/16” above the rubber for a deep positive grip to enable the operator to be able to do his job quickly and efficiently without spinning or side-slipping. Gripmasters are the best traction for skidsteers and are more effective than any other traction aid – especially chains. They are the only way to improve traction on tracked vehicles and they’re better than chains on wheeled vehicles like loaders, graders, backhoes, etc.
