Video Transcript for MaxxTow Surge Brake Actuator Coupler Latch Lock Review

AJ: What's up everybody It's AJ with etrailer.com. Today, we're going to be checking out this MaxxTow latch lock. What this is going to do, it's going to slide in this hole here on your latch on your coupler. That way you can't open it. If it's not connected to anything, nobody can connect to anything and take it from you, or if your ball is in here, it locks it to your ball. That way no one can disconnect it from your vehicle.

Let's check it out.There's a lock cylinder here. It's textured so you can kind of grab it. It gives you a little bit of grip, just that you can hold it and unlock. It comes with two keys to do that. Once you take it off, it's got a rubber cover just to cover up the lock mechanism.

That way no dust, grime, or any the elements get in there to erode it and ruin it for you. You can easily cover that up, and it's no problem. That'll put it on there. You don't have to push the key in there. Sometimes you have to have the key in there or twist it to twist it on.

This one you just push on, and it goes right into place. So now it's locked, and nobody can mess with the latch.Overall, it's black, e-coated steel. So it's going to hold up when you leave it outside. So you don't have to worry about the elements bothering it or eroding it or rusting it. It feels pretty durable.

Nothing's perfect, but it's definitely going to keep people from messing with your trailer. They're going to take one look at it and see it's got the lock whether it's attached to your vehicle or not and probably just go on to the next one that doesn't have a lock. They're not even going to bother with this one.Since every trailer is not the same, this does come in a couple of different sizes. What we're going to be talking about is this one's going to be 2-1/2", and that's the inside span here. The pin itself is a 1/4" thick. Now, the quarter inch thick pin is going to be the same on all of them, but the sides are going to be different. So if you need one that's a little bit smaller, your coupler is different than this, you can go to the 7/8, and again, that's from here to here. If you need to go bigger, you get 3-5/8, and that's going to be from here to here.Whichever one you decide to go with, they're going to keep your latch locked keeping people from messing with your trailer. Well, I think that does it. Thanks for hanging out, and I hope this helped.

I bought a coupler lock for when my boat/trailer are detached from my tow vehicle and I bought a pin dog bone lock for the coupler when boat/trailer are attached to tow vehicle like when parked at the lake boat in water.

I’m very happy with this coupler lock. I’m using it on a Maxey utility trailer with a Demco Easy latch adjustable coupler. It was a little long for my application, so I used a rubber grommet to protect the finish on the coupler. Great product!

Great service. Order showed movement the night I purchased the lock and arrived within a few days. Website was easy to use. Too soon to comment on the lock durability but I have a feeling if something went wrong they’d make it right.

I have a 2018 Ranger Trail boat trailer, and wanted a good lock to secure the trailer to my truck when I am off fishing. I went with the 3-5/8" to ensure that it fit well......... propably could have gone with the 3-1/2" and been fine. Looks good, I like the fact that it is a different type of key, which I hope is harder to pick, overall I am very happy with the purchase.

We have a flat trailer and a boat trailer that we wanted to be able to secure to our vehicle. With the unusual size we looked at number of places but like other "special" items we found them at etrailer.com. They shipped timely and are of a good quality.

Perfect for what I needed for the surge Brakes on my car EZ-Tow Dolly. I had previously ordered one that was 2-1/2" which should of fit but the hitch had some metal flares on it that made it necessary to get the longer one. Very good product - and I really like the round-cylinder key system. I recommend this product for anyone that has a surge brake system with the 1/4" shaft - pin locking system.
