About this Product

This solenoid is ideal for use in flat terrain, where it effectively stops or "blocks" the flow of brake fluid. The Reversing Blocking Solenoid is designed to prevent brake fluid from moving back towards the calipers or drum plates when your trailer is in reverse.

Installs directly in line between the trailer hydraulic actuator and the brake line.
Adapts to all models of hydraulic actuators; disc and drum.
Only one electrical connection is required between solenoid and vehicle backup light.
Dimensions: 7" x 4.75" x 2"
