StowMaster has been America's best-selling car-mounted tow bar since 1974. With ROADMASTER's telescoping Autowlok system, a single continuous motion allows one person to easily position and lock the coupler over the ball. Then, StowMaster automatically centers and locks itself as you drive away from stow to tow in 10 seconds! Moving components are made of stainless steel to prevent corrosion and to ensure smooth and easy operation. Self-lubricating nylon bushings eliminate friction between the inner and outer arms. 6,000 lb. carrying capacity. Weight: 48 lbs.
