Heavy-Duty Coupler Lock

etrailer Coupler Lock

The heavy-duty coupler lock, constructed of extruded, tempered aluminum, obstructs access to your trailer coupler to prevent others from hitching your trailer to their tow vehicle and driving off with your gear. The lock housing features a double-nickle chrome finish, and the shuttered keyhole protects the lock from the elements. Complete with a silver powder coat finish, this coupler lock is attractive, sturdy, and rust resistant.

etrailer Coupler Latch and Hitch Locks

To install this lock on your coupler, insert the key and rotate it to release the locking pin. Slide the lock body onto the flat lip of your trailer coupler. Push the locking pin into the hitch ball socket to engage, rotate the key back to lock the pin in place, and remove the key.

Durable Coupler Latch Lock and Hitch Lock

etrailer Coupler Latch and Hitch Locks

The adjustable coupler latch lock keeps others from unhooking your trailer after it's hooked up. Five locking positions fit coupler latch spans between 1/2" and 2-1/2" and sleeve-lock couplers. The hitch receiver lock secures your ball mount to your 2" trailer hitch.

Video Transcript for etrailer Hitch and Coupler Lock Set Review

AJ: What's up everybody, it's AJ with etrailer.com. Today, we're going to be checking out the etrailer lock kit. It's going to come with a pin lock, coupler lock, and hitch lock. Let's check it out.First up is our pin lock here. It's going to go through our latch and make it so that no one can operate it while it's in there. So if this is down on your trailer and it's attached, you can put this on there, nobody can unlatch from your trailer, or if your trailer is just sitting on its own, it's got the pin lock in there, you're not going to hook up to it.

You can't undo this to get the ball in there.The whole pin is made out of chrome plated steel and it's got a rubberize here for grip when you go to mess with the lock. You also got a dust cover there, that way it keeps the elements from getting to your lock core, which is key to life with everything here so you don't have to have multiple keys on you, I like that a lot. Easy to take off there, operate your latch and then when you get it on or just take the trailer off, it's easy to put right back. The pin works in a half inch increments so you're going from two and a half to two inches to one and a half to one inches to half an inch so that is about what gives you lengthwise when you're going to put it on your latch.Next up is our coupler lock. This is going to fit around your coupler and make sure that no one can hook up to it when you're not there.

Easy unlock there, you can see it's got the grooves here. It goes on the inside and you push this up and that locks where the ball would go. That way, let's just put it on there and show you, I push up on that on the bottom, turn the lock, now it's on there. Now, there is a little bit of movement, we do get questions like that, but it's not going to come off there and it's going to keep anybody from backing up there and trying to get a ball in there.Now, a couple of things about it, you're going to need a lip on your trailer coupler and it's going to be need to be two and five sixteenths. That's the only ones that this one will work with.

That way, it can slide on there easily and lock up into place. The whole thing is made out of a powder coat aluminum so it's going to hold up to those elements when you leave it out on your lot or whatever with it locked, it's not going to bother it.Now we get a lot of questions about this coupler lock like how much does it move around And like I said earlier, it does move back and forth quite a bit and a lot of people want to know if they can get a crowbar in there. You can see, yeah, you can get a crowbar in there on several points but it's more of a theft deterrent. In combination with this though, it's just a second guard against anybody messing with your trailer. If they really wanted to get to it, they could find a way, but this is going to keep people honest.Last but not least is our hitch lock.

This is going to lock your ball into your hitch, that way nobody can mess with it when you're not around. It's also a twist lock so you're going to spin this to slowly unlock it. That makes it harder to pick that lock because of all that's going on in the inside of this barrel here. See how it works on the inside and how it just twists here with the key and that's what pulls it tight and locks it. Much like the pin lock, it's made out of that chrome plated steel, it's got a nice rubberized end here to help your grip when you're turning the key on the other side and it's got that dust cover to help protect that lock core from the elements. Now for some measurements. You've got the diameter, that's going to be five-eighths, then the inside pin is going to be two and five-eighths and then the whole thing is going to be six inches long.This kit works together really well, I think it's a good option for protecting your trailer and your ball mount. Now, nothing's perfect and if somebody really wants to get something, they can find a way to do it, but this is going to be a good deterrent, maybe they're going to be like, "Nah, I'm going to go to that next trailer that doesn't have a lock on it. This one's all secured up, not going to mess with that." Plus, it's all one key so that's awesome too. That way, if you did eventually buy these all separately, you'd have three different keys laying around and you'd have to be, "Is this this one Is that this one That one" And that can just be a pain. One key is way easier. Plus, it's better be safe than sorry. Thanks for hanging out, I hope this helped.
