  • Weld-On
  • Demco
  • No Lockout
  • Straight Tongue Coupler

Surge-type actuator features a corrosion-resistant composite master cylinder and a primed finish. Adjustable channel lets you mount different coupler attachments (sold separately) in 1 of 3 positions. Weld-on application.


Features:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • Adjustable channel has 3 different mounting positions for coupler (sold separately)
  • Composite master cylinder is durable and efficient
    • Glass-reinforced nylon construction resists rust and corrosion
    • Large reservoir provides increased capacity for brake fluid
    • Automotive-style diaphragm cap creates completely enclosed system to help prevent contamination of fluid
  • Breakaway lever activates your trailer's brakes if the trailer disconnects from the tow vehicle
    • Snap hook on safety cable ensures secure connection to lever
  • Acetal copolymer lining provides smooth operation as actuator telescopes in and out
  • Heavy-duty steel construction
  • Primed finish
  • Weld-on installation
  • Made in the USA


Specs:

  • Application: trailers with hydraulic drum brakes
  • Gross towing weight: 12,500 lbs
  • Maximum tongue weight: 1,250 lbs
  • Channel width: approximately 3"
  • Channel height: 8"
  • Mounting: straight, 3" wide trailer tongue
  • Model number: DA10
  • 1-Year warranty


Note: Because this actuator 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 the actuator triggering your trailer's brakes.


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 hydraulic actuator is triggered as your trailer moves forward, once your tow vehicle starts to slow down. When this happens, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage your trailer's brakes.


Adjustable Channel Design

The adjustable channel on this trailer brake actuator allows for ultimate versatility. Mount almost any type of coupler (sold separately) - from a standard ball coupler to a lunette ring or clevis attachment - to fit your specific application. In addition, the 3 mounting positions on the channel let you adjust the height of the coupler. Just place the coupler so that it matches the height of the ball mount or other hitch attachment on your tow vehicle and you will be able to tow your trailer levelly.
