The Kelley KMWC Series manual wheel restraint provides a cost-effective and easy-to-operate solution for restraining unconventional vehicles. Mounted above ground, the manual SURFACE CHOCK is easy to install and requires minimal maintenance, creating a lower lifetime cost of ownership than other wheel chock systems. Its user-friendly, two-step engagement/disengagement only requires 35 lbs. of operating force, and its ergonomic design requires no bending or lifting for safe and accurate operation. In addition, the simple yet durable design includes an interlock-capable control panel, standard LED communication lights, exterior audible alarm and advanced safe engagement sensors to provide effective and efficient communication between the dock employee and the restraint operator.
