Roadmaster 501 6,000 lb Stowmaster 5000 Tow Bar

6,000 pound weight capacity car-mounted tow bar * Stainless steel in virtually every moving component for smooth, trouble-free operation. * Autowlok locking mechanism - allows both tow bar arms to extend or retract for a quick connection. Then, as you drive away, the arms self-center and automatically lock. * Full-length safety crossbar - a full-length angle iron brace is integrated into the rear of the bar for maximum support. * Self-lubricating nylon bushings eliminate friction between the inner and outer arms. Other tow bars use steel on steel. * Plug-welded arms - steel plugs seal both ends of the tow bar, preventing corrosion from moisture and debris. * A lustrous, high-tech powder coat finish for maximum durability.
