Actuator, Model 20, Drum, 2-5/16″ Ball, Weld On, 20,000 lbs.

Actuator, Model 20, Drum, 2-5/16″ Ball, Weld On, 20,000 lbs. Adjustable-channel, surge-type actuator welds onto trailer tongue and lets you mount the included lunette-ring coupler in three different positions to match your application. Unique roller design helps reduce resistance. When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the actuator is triggered as your trailer moves forward while the tow vehicle slows. The actuator telescopes, applying force to its master cylinder, which in turn supplies the necessary hydraulic pressure to engage the trailer’s brakes. Features: Hydraulic actuator synchronizes trailer brakes with tow-vehicle brakes Unique roller design reduces resistance during telescoping to create straight-line movement Sturdy, durable steel construction resists bending in jackknife situations Standard, heavy-duty coupler Breakaway kit included Primed finish Weld-on installation Specifications: Application: hydraulic drum brakes Ball size: 2-5/16″ Mounting: 3″ wide channel tongue Capacity: 20,000 lbs. Maximum tongue weight: 2,000 lbs. *Because this model does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without triggering your trailer’s brakes.*
