Video Transcript for Review of Blaylock Industries Lunette Ring Locks - BLTL-60

Jeff Hello everybody, this is Jeff at Today we're gonna take a look at this Blaylock aluminum EZ lock trailer coupler lock for lunette ring couplers. Now this coupler lock will help prevent theft of a trailer that has a lunette ring coupler on it that accepts a pintle hook. This lock is a nice aircraft-grade lightweight aluminum construction. It's very strong, resists wear and corrosion. Does consist of these two heavy-duty cast aluminum discs that'll fit inside your lunette ring coupler.

And then this 3/4 inch diameter steel pin that'll slide through the center of the lock. So once these are in your lunette ring coupler, you just slide this up through the center and then you'll lock it in place with a padlock. Now it does require a padlock to lock the pin in the lunette ring and keep it from being removed. Now I do wanna show you what we're talking about. Here's a lunette ring, and this will work.

This lock will work on either a 2 1/2 inch or 3 inch lunette ring, meaning the inner diameter measurement. This one happens to be a 3 inch diameter one, so it'll work on that. And I mentioned it does require a padlock. I happened to pull the padlock that it needs. It's this Master Lock padlock.

We sell it separately on our website, it's part number ML40D. Now this part number, it does not include the lock, so you would have to buy that separate to add for this, But just to show you how this works, what you'll do is take one of the disk, the pin, and it goes up through the bottom, take the other disk, slide it over there, then you have your hole right here. And then what you'll do is just open up your shackle, turn it to lock it, take out the key, and that's locked into place. And it keeps those two disks in the lunette ring. Keeps anybody from coming up to your trailer that's unattended and they hook their pintle hook up to it and just take it away.

So with this in here, there's no way they're going to be able to hook up to it. And then to remove it, all you have to do is take your key then, put it back in there, remove the shackle. And as I mentioned in this part number that I'm demonstrating here, this lock is not included. Now we do sell the lock separately by itself, it's ML40D. We do also sell the complete kit if you want. And that would be this lock here with the padlock. And that goes by part number BLTL-60-40D. And usually these products that I'm mentioning that we sell separately are listed on the product page of this one here I'm going through. This part is made in the USA. Few specs on this again. It is designed to fit most lunette ring couplers that have a 2 1/2 inch or 3 inch diameter eye, and the weight on this lock is only about three pounds. But that should do it for the review on the Blaylock aluminum EZ lock trailer coupler lock for lunette ring couplers..

This rugged, rustproof aluminum trailer coupler lock simply yet effectively deters towaway theft of your trailer that has a lunette-style coupler. Fits lunette rings with 2-1/2" or 3" inner diameter. Padlock sold separately.


an excellent product that complies with our security protocol.


eTrailer is our go-to for all of our trailer needs.
Great products & great service!


After searching for awhile for ways to effectively lock our pintle-hitch trailers I was happy to have come across's Blaylock Industries EZ Lock Lunette Ring Lock!! This product fits our needs perfectly! I would definitely recommend/ will purchase again for future trailers.


This is the perfect locking mechanism to secure a trailer with a pintle hitch. This is my second purchase of this product for a new trailer I just acquired. It's a good price, easy to use, and works well.


So far so good. When I ordered the item, your operator seemed to want me to have ups deliver it or pay the lower rate of snail mail and they said it would be up to two weeks before I received it. I decided to go the cheaper route of the us postal service and I received my item within only a few days. Just felt like I was being nudged in the more expensive direction. Other than that, I'm happy with said product. Thanks

Awesome! I love the Lunette ring locking mechanism. It keeps my stuff safe in the middle of nowhere, everywhere.

Pics attached.


Purchased to help secure a valuable portable generation unit. Needed something to help prevent theft along with other measures to protect this high value piece of equipment. We use a keyed alike shield master lock instead of a disc lock to try and shield the pin from direct breach.


A very simple but effective product that provides good security for the lunette ring on my trailers.


The head of the pin is not much larger than the hole in the disk. I thought it might be easy to drive it through the aluminum disk, so I bought a steel washer to prevent that. I think that would be a good product improvement. Otherwise it works well and the delivery was quick. Thanks.


Great product!


Items received were of high quality and as advertised. Still extremely satisfied with purchase even one year later.


love the item looks good and makes the trailer safe from theft


Product is good , but a little bit loose on the eye but generally speaking it gives you a piece of mind in the safety of your equipment.


Well built deterrent!!!
Only shop Etrailer!

The BEST!!!


Fits well and lightweight. Looking forward to seeing how they weather.


Great price and works with our standard locks.


Exactly as expected. Customer service provided timely updates for delivery.


Simple easy solution. Would give 5 stars if design had only one piece. Lighter than expected.


Exactly what I ordered


A great product at a great price and very good service.


Works exactly as advertised.


Everything I needed in one store, I bookmarked this page.


Works great


product was perfect


Review from a similar EZ Lock in Lunette Ring Locks

First I must say etrailer is great to work with. Customer service 2nd to none!! Now the wheel lock: Looks nice and works OK. I’m still not convinced it is securely attached to vigorously prevent a determined thief but it does look tough! Of the three lock settings smallest is too tight, medium is just a little loose. The box it came in showed protective caps on the ends. Mine arrived with no rubber caps. It does scratch my nice teardrop custom wheels.

I checked with Blaylock and the rubber caps are no longer included.

  • 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 Recommendation for a Trailer with a Lunette Ring
    We do have a lock for a lunette ring, but lock # 379DAT will not work. You will want to use the Blaylock EZ Lock, # BLTL-60. The 2 cylinders fit inside the ring and then a pin is placed through them and padlocked on one side so no one can hitch up the trailer without first removing the lock.

  • 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. This lock has a 1/4 inch diameter pin that is 2-1/2 inches long and has a covered key slot that prevents corrosion. Another trailer coupler lock I would recommend would be the Master Lock Adjustable Trailer Coupler Lock, part # 2847DAT. This coupler lock has a 2 inch shaft and may provide a more snug fit for the...
