This beefy surge actuator engages your trailer's disc brakes and keeps them from locking up when you shift into reverse. EZ-Latch coupler is a big improvement over finnicky trigger latches. Primed, ready to be welded and painted. Made in the USA.

Electric reverse lockouts can be summarized in one word: convenient. If you're looking for an actuator that lets you "set it and forget it", this one from Demco could be a great option for you.
The solenoid on this electric lockout ties into the reverse light circuit on your 5-pin, 6-pin, or 7-pole connector so that your disc brakes won't engage when your reverse lights come on. This can make backing up a boat or construction trailer so much easier than using a manual lockout because everything is automatic.
Few things matter in towing as much as a secure connection to your hitch ball. The thing of it is, some coupler latches don't really have a way to show you that they have a firm grasp on the hitch ball. You either just have to eyeball it or try to wiggle the coupler latch until it closes. And if you opt for just trusting your coupler and assuming it's on there, you might not notice the gap between the ball and your coupler's ball socket, an issue known as highballing, until it's too late and you lose your trailer on the highway.
That won't be an issue with the EZ-Latch on this Demco actuator. Just center your coupler over the hitch ball, and lower your trailer tongue as you normally would.
As the coupler's socket slowly accepts the hitch ball, you'll see the latch rise. Keep lowering your trailer tongue until you hear the metalic clink . When you do, you'll know for certain that you've got a good, strong connection, without the need to tug or wiggle the latch into place. This gets you on the road a little bit quicker and with a lot more confidence.
The EZ-latch is so easy to use that you don't even need a safety pin to keep the ball secured inside the socket. But you can, as a theft deterrent, put a locking pin through the dedicated hole on the side of the coupler.
You might see the phrase "hard plastic" and think, how durable could that really be? But the truth is, it's tougher than it looks and you'll probably never break it.
Its real name is acetal copolymer. It has a self-lubricating surface. It's extremely resilient, durable, and smooth. And it wears well over time. In fact, this same can even be found in some automotive applications, making it perfectly suited for a telescoping brake actuator on a boat trailer.
When you slow to a stop as you're towing, momentum pushes your trailer toward the rear of your vehicle. When this happens, the surge brake actuator compresses the master cylinder inside, which forces it to push hydraulic fluid out to your brake lines, ultimately engaging your trailer brakes. When you start moving again, the actuator will telescope back out, stopping the flow of fluid back to the brakes and allowing your trailer's wheels to start rolling again.

Hello everybody, this is Jeff at etrailer.com. Today we can take a look at the Demco Hydraulic Disc Brake Actuator with the electric lockout and it's for a 2 and 5/16 diameter ball. Has a 20,000 pound gross toying weight capacity and you can see it's in a nice prime finish. Now this hydraulic actuator will activate your trailer's brakes when the tow vehicle slows or stops. Basically what happens is when you apply the brakes in your tow vehicle, deceleration occurs, and the momentum will push your trailer toward the rear of your vehicle. So with a surge brake system like this, this actuator's then triggered as the trailer moves forward once your tow vehicle starts to slow down and when this happens, this actuator will contract, applies force to the master cylinder back here.
And this in turn supplies the necessary hydraulic pressure to engage your trailer's brakes. This one uses a nice acetyl copolymer lining which provides a nice smooth operation as the actuator will telescope in and out. This one does use an easy latch coupler mechanism for a nice, simple, secure hookup and disconnect. Basically, it'll let you hook up when this latch is in the closed position like it is now, you just drop the coupler over the hitch ball and the latch will snap into place. You don't have to get out, open it, close it.
I wanted to try to demonstrate that. I happen to pull, here's a 2 and 5/16 size hitch ball. So if I can lift this up and you can see if I put it on there, with it on there, and then you just put the weight, push it down. If you noticed, it snaps right into place. That lever snapped into place to keep it there and you can see that you're connected.
No problem. So you don't have to open and close the latch all the time and you just leave it in this position. Now when you go to disconnect you just pull up on the latch it's a trigger latch right up here, release it, whoops. And then you'll be able to see once you put that up in the up position, it releases it. You can take it off the ball and now you're detached.
Simple as that. So it makes it very easy to connect and disconnect. And you swing this back over here. This is a heavy duty steel construction. Has a sturdy reinforced outer casing, as we mentioned, has a nice prime finish to it. Now the master cylinder in the back here it is a heavy duty aluminum master cylinder. It's very durable, rust proof, and efficient. It is built for high pressure applications and allows 50% greater displacement than a standard master cylinder. Under this shield back here, you should be able to see there is an electric reverse lockout solenoid. This will let you back up without actuating. your trailers brake. Basically that's solenoid will activate automatically when you shift into reverse. It does have wires on it, so it does have to be wired into your trailer connector, which will then connect your tow vehicle so that it can detect when you're in reverse. It does come with the breakaway cable and the latch hook. That's all included and it is required by law cause this will prevent a trailer runaway situation. And the way it does that is you take your hook, has a latch on it, and you, when you hook up your trailer to your tow vehicle then you take this hook and hook it to the tow vehicle. And what that does is in case this comes detached from the tow vehicle, it will pull on this cable which would activate that lever, which again would allow the pressure in here, supplies the pressure to engage the trailer brakes in a runaway situation. So again, this breakaway cable comes, is included, and it is required by law. Now this is a weld on installation. It is designed to mount to a straight 3 inch wide trailer tongue. It is made in the USA. Specs again, this is, for trailers with hydraulic disc brakes. Gross towing weight capacity is 20,000 pounds. Tongue weight maximum is 2,000 pounds. And this does also go by a model number of DA20. But that should do it for the review on this Demco Hydraulic Disc Brake Actuator with the electric lockout for a 2 and 5/16 diameter ball. Has a 20,000 pound gross towing weight capacity.
Very high quality product. Super fast delivery.
Heavy duty. Bigger and heavier in person. Feel confident with that trailer behind you. Worry about other things instead of your trailer.
Nice quality.
Very well make Surge Brake Hitch. Excellent quality. etrailer always has what you need at a good price. Excellent company.
Arrived in good condition, although box was in bad shape. Just got it and disassembled to fit up and weld on 1978 Airstream 31' Excello 500. Will have to reposition jack and possibly propane tank mounts. This trailer originally had a vacuum brake booster. will update when installed.
Awesome on-line experience. The way it should work.
Thanks Amy
I received the coupler on time but was missing the reverse solenoid. My installation was a little unique do to replacing a super short Atwood unit. I also had to modify the channel as well, you may not have to for your application.
unit is heavy duty
arrived promptly
replaced actuator on utility trailer, updated frame and axles, was time to complete with correct weight actuator,, went from 7k to 12.5k and has by pass for auto back up anti lock.. this is mcuh better than non by-pass type
