Arrives before Christmas 
This surge actuator lets your trailer's drum brakes work without wiring or a brake controller, so nothing electrical sits in the water. That makes it ideal for boat trailers. And when it does get wet, the zinc plating helps keep it from rusting.
This Demco DA75 actuator is built for life at the boat ramp. Its zinc-plated body resists corrosion when exposed to saltwater, and the master cylinder is sealed with a diaphragm cap and a booted push rod to keep moisture out, so you can use it in coastal or brackish water environments.
The EZ Latch coupler drops onto a 2" hitch ball and clicks shut on its own, even if the latch is already closed. You don't need to hold the handle while you work the jack or line up the ball. That keeps fingers out of the pinch zone and makes it faster to hook up by yourself. After it clicks, give it a firm tug to confirm the catch, then add a coupler lock (sold separately) to help deter theft while you're away.
The color coded decal on the emergency lever shows red when the breakaway is engaged and green when it's released, so you can spot a tripped system before you tow. Bear in mind, this isn't a parking brake. If you're on a slope, use wheel chocks and your truck's parking brake to keep your trailer from rolling.
Inside the actuator, a spring-loaded push rod controls line pressure while an integrated dampener reduces impact shock. That gives you more predictable braking even when your load shifts or weight fluctuates.
