Video Transcript for Blaylock EZ Lock Lunette Ring Coupler Trailer Coupler Lock Review

What's up everybody, it's AJ with Today we're gonna be checking out this Blaylock, which is gonna be a lunette ring lock. What we're gonna do is just simply unlock it, set it down into place, just like this. We add our padlock, and remove our key. And now you have a lock on your lunette ring, so nobody can just back up your trailer and attach to it when you're not around. Does gonna come in two different kits.

You can get it without the padlock and with the padlock. The two plates on either side of the lunette ring are gonna be made out of aluminum, and then you have steel pin in between them, and then the lock itself is gonna be a stainless steel. So you don't have to worry about leaving this outside on your trailer. It's designed to be out there and be able to handle those elements. This is gonna work with lunette rings from 2 1/2 to 3 inches on the inner diameter.

Now I will say that we had issues with it on a trailer that was close to 2 1/2 inch diameter size. It just didn't fit down there well enough 'cause it's got to fit down in the ring so you can get that pin through there and attach that lock at the bottom. So just be careful on your trailer to make sure that it's gonna fit that. We have a lot of reviews online saying they really like it. They've had it for a year or so, and they use it on a bunch of their trailers that they have and they've had no issues whatsoever.

So it really does a good job of locking that up and just keeping people from messing with your stuff when you're not around. Well, I think that does it. Thanks for hanging out, and I hope this helped..

Exactly as described. Great fit.

Trailer hasn’t been stolen and it looks like it’s new
Bill - 10/12/2022


Works great, cheap and now thugs will have a much are time stealing my trailer! Well worth the money.

Quick update since its been over a year of what use. Good news, so far no one stole my trailer and absolutely no issues with the pintle lock. Great product!
David F - 08/06/2018


The coupler lock is easy to use and should deter the easy theft of my trailer. Because it is designed for both a 2.5" and 3.0" lunette ring, there is some play between the lock and my 3.0" ring, but not enough to impact its intended function.

The lock works great...the aluminum does not rust or corrode when left outside in the elements
Thomas S - 08/10/2016


If you have a lunette ring based trailer, this is the lock to use. Simple and solid design and the Master lock is pretty weatherproof.


It fit the pintle hitch on my brush chipper, perfectly. After having one stolen, I wanted to make sure this one did not leave my possession, and this looks like it will take care of that.

This works so well, I have bought a couple of more since, to use on other equipment.
Stephen R - 01/17/2017


Looks great, works great, does exactly what I needed.
If I need another I will definitely be reordering


Really good product, we’ll take our military trailer to trail rides and leave it at the camp site and with this lock I don’t have to worry about it getting stolen. Real easy to use


I purchased a BLTL-60-40D Pintle lock about a year. I use it to keep my trailer locked. I am very happy with the purchase and it has worked flawlessly.


We like these so much that we bought mo re.


These locks are easy to use and we haven't had any trailers stolen since we started using them. They are easy to use and have been holding up well despite MN weather and constant use. The keyed alike locks are great and the customer service at etrailer is top notch.


This is the second coupler lock I have ordered from etrailer. Delivery was very quick and the product is just what I was looking for. Price was the best around too. Very satisfied overall and will be ordering from etrailer in the future.


The lock is working perfectly. It is keeping my co-workers from "Borrowing" my trailer. I appreciate you checking in to make sure I'm still satisfied!


Having had one brush chipper stolen, I was not about to let it happen again. This lock works perfectly on the pintle hitch on the chipper. It was shipped fast and was just as advertised.


Have been using this product for over a year on 2 different trailers. I sleep well at night knowing there is no possible way anyone's going to take either 1 of my trailers. Nothing to corrode and they look like the day I took them out of the package and most my trailer stay on oceanfront jobs on the east coast of the Outer Bank, nc.


fit every pintle hitch trailer i have. sturdy construction and i love that they can be keyed alike


Good quality. Is holding up after a year of use. My trailer stays in the garage most of the time, so this only gets used when I am out camping or leaving it in the drive way on occasion.


very strong Lunette Ring Lock. very easy to install


Haven't used the product yet but the customer service getting these out to me was outstanding!

Whenever I have trailer needs I'll definitely be back to



Fits trailer ring perfectly
Keyed alike
for both locks and trailers
Luv it


Just received recent order from E-Trailer. Fast shipping as always. Thank you! You guys have never let us down.


Feels very light and it is very sturdy. Fits great on my trailer. I needed something that will hold through "old winter" and this one fit the bill.


Installed as expected and certainly looks as though it will protect against one of our local thieves from driving off with our huge generator. Certainly coming back for some other products.


Easy online ordering, product arrived on time and exactly what I ordered, thanks etrailer.


Product was delivered on time and fits the hitch on my Vermeer Chipper perfectly.
Solid construction and I’m happy with the purchase.


excellent as advertised would purchase again thanks etrailer

  • Is Blaylock BLTL-60-40D Lunette Ring Lock Available Keyed Alike
    The Blaylock # BLTL-60-40D isn't available with keyed alike locks, but you can purchase just the assembly that installs into the lunette ring, part # BLTL-60 by itself and purchase keyed alike locks separately. The Master Lock # ML312KA would be a good choice for a keyed alike lock. Simply choose the 'keyed alike' option from the drop down menu on the linked product page.

  • Trailer Coupler Lock For Pintle Hook / Hitch
    We have a few options that you may wish to consider. If you are looking for a lock for the hook or hitch alone, I would recommend our coupler lock, part # e98887.
