Extensive Testing


InfiniteRule products undergo extensive third-party testing to determine shear strength.

This lock has a shear strength of 32,000 lbs.

Video Transcript for Review of InfiniteRule Trailer Hitch Lock - Stainless Steel Hitch Lock Set - IR36FR

Hi there. I'm Michael with etrailer.com. Today we're gonna take a quick look at this InfiniteRule hitch lock set. Now this set is going to give you three of these flush style 3/4 inch diameter hitch locks that will secure your ball mount or accessory to your 2 1/2 inch or 3 inch hitch. This will work with the Gen-Y Mega Duty ball mounts as well as the Fastway Flash HD adjustable ball mounts as well as your other 2 1/2 and 3 inch hitches. This is made here in the USA, heavy duty stainless steel so it is going to be very durable for you.

It is third party tested to have a sheer strength of 32,000 pounds. So it is gonna work with those heavier duty ball mounts. As far as our dimensions go, you can see our overall length. We're gonna be looking at approximately 6 1/2 inches. Our inside pin length or our span from here to here, we're looking at just shy of four inches, we'll call it 3 7/8 of an inch there.

This does have the grooved pinhead that's gonna be very easy to grab. We also have the weather resistant tethered dust cap that's gonna help keep water and debris out of our keyways. We get three keys, one for each lock, but they will work. So between the locks, they're all keyed alike so just have to use one key for all three. Then you'll have a couple extras on hand.

You can see we just simply twist the key or we can twist the other end, make it a little bit easier on ourselves to get that to come out. Inside we do have the O-ring here that's gonna protect the internal components from dirt and grime getting in there, and so very simple to operate. Just slide the pin through and twist it in place to get it locked nice and tight for us. So if you are looking for three matching locks for your ball mount, this is gonna be a great way to go. Just have the one key on hand, be able to take any of them off that you need.

That completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

So happy with this lock. Been looking everywhere for 1. Fits my gooseneck perfectly and I feel safer now that my new air ride shock absorber hitch is now locked on. Thank you. Fast ship as usual , great service



by:

Excellent customer service from Quinn… these locking pins are exactly what need for our Roadmaster tow bar. The Jeep will be much more secure now when we are on the road.



by:

Great product, wanted to discourage thieves from taking my trailer, this keeps the coupler tube locked so it can’t be slid out. Did exactly what I was looking for.



by:

These locking pins are not only completely functional,
but are an addition to the look of my vehicle! I now have five of these on my jeep, and look amazing!



by:

Works for the hyperhitch 9” adjustable drop 3” hitch. Needs two 3/4 pins if no pintle accessory and three if pintle accessory. Has the prefect span .



by:

Although trailer theft is rare, I highly recommend this lock pin for your gooseneck combined with a hitch lock to prevent and deter the idea. Especially when having to leave your trailer unattended in a public parking lot or on the job. The simplest solution at a great price.



by:

The Hitch lock is definitely a deterrent. It's made of great quality material. It is standing the test of time from harsh weather and tampering. I highly recommend this hitch lock. We're purchasing another.



by:

Shackle pins look great!
Functional,
and we'll made!



by:

Fast delivery and fit perfectly in the Blue Ox BX88357 aftermarket bumper adapters.



by:

The product is great, getting it from ETRAILER is the problem, 2nd time had to order this, 1st time I ordered this part with 2 trailer rims that were said to be in stock, waited 10days for them to tell me they're waiting for the rims to come in from backorder 6months from now so we can ship everything together. It's spring I'd like to use my trailer before now. Poor customer service!!



by:

Woks as should gives me peace of mind great product



by:

Fit and worked great



by:

Works great



by:

High quality product. Fantastic fit and finish.



by:

I was grateful for the ease of use of the website and the online portion of my transaction. Everything was very clear and function and seamlessly. I’m also very pleased and grateful the product that I purchased arrived in good order today, which was very prompt and it’s quite clear that it is great value in the product for the money and professional grade.



by:

This is the simplest and most effective lock I’ve ever used, I pull my bulldog hitch off, then install the locking pin when my trailer sits that takes two minutes or less to secure…



by:

Excellent gooseneck lock. Solid, fits snug and is extremely well built. This actually feels more robust than the pin that came with the trailer. Love that it’s stainless and the key mechanism works very well. Highly recommended!



by:

Great product. Quick shipping by etrailer as always. I had an issue with the lock for my application (my problem for not reading the discription completely) so I called InfiniteRule Security directly and their customer service is second to none. I highly recommend theit products. After a year, I have had no problems with the lock.



by:

I have a Gator Made 40 foot utility trailer and after speaking to a couple of your representatives, I decided to try this hitch lock (we weren't sure if it was long enough). Well, it was!! I'm impressed with the product. Very solid. And now, I can sleep at night knowing that my trailer is secure from theft.



by:

Perfect for the application. Finish has remained intact for a year of medium use. Shipping was prompt and the product is exactly as I expected. Can’t go wrong.



by:

Great product looks great perfect fit delivered the very next day!!!



by:

This locking pin adds a bit of security to my new LQ horse trailer. I have a coupler lock for the gooseneck, but realized the gooseneck can be removed by simply pulling the unlocked pin. Problem solved!!!



by:

Replaced the quick pin with this locking pin to help prevent someone from easily stealing my expensive shocker air hitch. Nothing is 100% safe from thieves, but for the money it’s well worth it.



by:

Great lock for my gooseneck.



by:

1st of all I think it's a little overpriced for what it is. But it works. also you say it's for a Gen. Y coupler it also does the shocker gooseneck coupler Shipping time was great.
