Extensive Testing
InfiniteRule products undergo extensive third-party testing to determine shear strength. The shear strength is determined by placing the locking pin in a stress position and subjecting it to increasing force until a required proof load (maximum force received without deformity) is met or the pin fails. These locks have a shear strength of 42,000 lbs.

Hi, everybody. Andy here with etrailer.com. Let's take a look at this InfiniteRule trailer coupler lock. This flush style coupler lock is going to secure the trigger latch on your trailer's coupler to deter theft, and the trailer can't be removed from your tow vehicle when it's locked onto your hitch ball. Now, this is going to offer a convenient one key operation, and as you can see, two keys are included with this, and this weather resistant tethered dust cap is going to keep water and debris out of the keyway. And let me go ahead and just show you how to unlock this and open this.
So I'm gonna stick one of our keys in and then just turn this counterclockwise. And then that's going to loosen this lock up as I keep turning, just turn this like a screw. And so as you can see, that brings it, you're able to take the lock apart. I did wanna point out that there's an O-ring here that's going to protect the internal components from dirt and grime. And the diameter of this pin is a quarter of an inch.
And this is made here in the USA of a heavy duty stainless steel construction. And let me go ahead and bring a coupler out here, just an example of a coupler, and show you how you would operate this in case you don't know. I'm just gonna slide this through here, through our trigger latch here, and then line this back up like so. And then I'm gonna turn the key clockwise and then that's going to bring my lock together, tighten it up. And then I wanted to show you, and hopefully you can see, around the key ring, we do have these marks or hash marks and that is to let you know, once you have this nice and tight, you're just going to back off to the nearest hash mark there around that ring and then that's going to allow you to remove the key and then you replace your cap.
And as you can see, that's going to do a great job of keeping your couplers secure on your hitch ball and you're not gonna be able to unlock that. So again, just to remove this, stick the key in, turn counterclockwise like a screw. Remove it and get my coupler out of the way here. So as I said, this is made of heavy duty stainless steel construction, so you're not gonna have to worry about rusting. So again, I've got this nice and tight.
I'm just gonna back off to the nearest hash marks there, pull the key out, close my cap. Now, I wanted to point out in case you didn't know that InfiniteRule products do undergo extensive third-party testing to determine shear strength. Now, the shear strength is determined by placing the locking pin in a stress position and subjecting it to increasing force until a required proof load or maximum load received without deformity is met or the pin fails. So this locking pin has a shear strength of 42,000 pounds. Now, just to give you some measurements here, the overall length of this pin, we're sitting a little over three inches, about 3 1/16 inches long. And inside pin length or the span or also called the usable pin length, looks like we're sitting right about 1 5/8 inches on that inside pin length. And this does have a limited lifetime warranty from InfiniteRule. Well, that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

It looks like it’s a nicely built tongue lock system. When it was delivered and I opened it, the finish was already scratched. Kind of strange, as it was packaged nicely. Should also be a great visual deterrent.
Even tho this wound up not working with my trailer, the lock seems well built and sturdy. Maybe I'll find a use for it down the road.
Nice locks seem to be really well made. They look great too.
I had a similar type coupler lock on my utility trailer that had begun to corrode because it was not made of stainless steel. I am using this one on my new vacation trailer along with an extreme duty coupler lock.
Love it! It’s solid and well made. Just make sure you order the right span length for your trailer lock. I paired it with the Bulletproof Hitch lock. My trailer is safe!
Pior to purchasing this lock from etailer I bought several competitive trailer lockks from big box stores. All were junk compared to this one. I was hesitatnt to purchase when I saw the price but I would have saved a lot of money and disappointment had I purchased this one first. I will not stop a very determined thief with power tools but ti is far superior to anything else I tried.
Excellent product. I am very pleased with it, and with the customer service I experienced.
Going to work great-thanks for the help selecting for my Dexter C200 hitch.
This product was as advertised and fit nicely on my 2 5/16” coupler. There weren’t any instructions included with it but it was pretty straightforward to figure out how to install it. I am looking forward to using it the next time I go fishing.
Quality locking device!
Fit perfect!! I tried another and it didnt fit this one is like a glove. Can look in site and see where order is in queue.
Love the lock!
I searched everywhere for something like this. I like that it's nice and hefty and seems like it will be secure. I have the new Wallace Forge coupler on my RV which requires a wider span than the smaller one's. This fits my coupler but I do have one complaint. The pin is only 1/4 inch diameter and my coupler has a much larger hole but your site did not carry the larger pin, so I had to settle. If you have the larger pin I would be happy to exchange the 1/4 inch pin.
The coupler functions as advertised. Ease of installation and a visual deterrence for “courious” passersby. I would definitely recommend this lock.
Very smooth working lock assembly.
Finally found a couple lock that not only fits, but also looks like it's very durable. Thank you!
Nice and heavy duty
Fit just as I expected after taking a measurement and after looking at most 1/4” pin locks for sale, I think this one is the most robust
