Duty tow straps are designed to free stuck or disabled vehicles from mud, sand, or snow. The strap has a loop sewn in each end that slips easily onto a frame mounted tow hook. The webbing stretches up to 20% during use and then recoils to its original length. The forward momentum of the towing vehicle PLUS the recoil action will all but guarantee success when you are really stuck. Available up to 20,000 kg or over. for farm tractors, trucks, and heavy equipment.
