570 Slack Reducing Coupling

When vertical clearance is at a premium, the 570 slack reducing coupling may be your solution. Our 570 offers a bottom mount air chamber, low profile, and strong latching system. An oil cup is provided to quickly and easily lubricate the latch. This coupling must be used with an air service chamber. We recommend our 281C. With a maximum gross trailer weight of 90,000 lbs. and 20,000 lbs. latch capacity, this is the perfect product for your heavy-duty applications.
