The Kelley STAR2 is a manually operated trailer restraint system with an exclusive sensor bar and an effective light communication system. The sensor bar on the STAR2 automatically senses the actual contact between the hook and the vehicle’s rear impact guard, and it communicates the status via interior and exterior red/green LED lights. The push bar is easy to use for manual activation and release. Requiring low maintenance, the STAR2 provides exceptional value for a low cost of ownership.
