Serco Pit-Bull Truck Restraint Model SL40

The Serco SL40 Series Mechanical Vehicle Restraint is a manually operated vehicle restraint system like the SL20, but the SL40 automatically senses the actual contact between the restraint and the vehicle’s rear impact guard and communicates its status via interior and exterior red/green LED lights. The control bar allows for easy manual activation and release. The SL40 provides exceptional value and a low cost of ownership.
