Great design that protects against crowbars.

Fast shipping, arrived right before my new truck trailer was delivered. No scratches, well-protected packaging. The second you feel the weight of this thing in your hand, you know you bought the right product.

Keeps our construction trailers secure overnight.

Excellent anti-pry design. It keeps the most vulnerable part, the lock cylinder completely shielded under high quality steel housing. A standard crowbar won't do a thing against this. Very smart engineering.

Tristan Wolfe
Better than my old noisy U-lock

Even though it has some serious weight, the design makes it easy to handle. As a woman, I had zero issues putting it on. Just turn the key and it locks right onto my 2" coupler perfectly.

Watch the website video for easy install.

The installation process requires watching the video. It's different from my previous one. I thought I could successfully install it, but unexpectedly, I still needed to refer to the instructions.

Don't worrying about thieves stealing my RV.

This lock is awesome. My RV has a 2" coupler, and once this thing is on, I don't have to stress about thieves driving off with it.

Q
Quincy Bell
I really love this new trailer lock so much!

This trailer lock has a handle. The handle means you don't have to hold it up. You can carry it to install it, which saves a lot of trouble.

Perfect waterproof lock for my jet ski trailer.

Looking at the pics online, I was worried it might feel like cheap plastic, but man, was I wrong. It's got that heavy, solid steel feel, and the black rust-resistant paint is perfectly even. Incredible value for the price.

Damian Mills
That handle saved my toes more than once!

The unique design is what caught my eye, so I opened it immediately when it arrived. Love the black finish and the orange dust caps it came with. The built in handle is genius makes it easy to carry without worrying about dropping this heavy thing on my toes.

Now I can relax without checking on my truck.

4 keys is a lifesaver for someone forgetful like me! The dust plug fits nice and tight so it won't just fall off. The overall craftsmanship is clean with no rough edges, fits my coupler like a glove.

Forrest Price
Still working perfectly.

Highly recommend to anyone with an RV or trailer. Don't cheap out to save a few bucks when it comes to protecting an expensive asset. Go heavy-duty.

Easy 5 stars for standard trailers.

Easy 5 stars. It fits most standard RVs out there, works perfectly for my 2" coupler. If you have an older trailer model, just check the dimensions first so you don't deal with returns, but for standard setups, it's a perfect match.

Love having extra keys and the dust cover.

Top notch quality. Exactly what I was looking for. 10/10 recommend.

Lewis Grant
Arrived just in time for our camping trip.

I drive an F150 and haul my utility trailer for weekend jobs. This lock pairs perfectly with it and holds tight. Best part I can leave my rig curbside to grab a coffee without constantly looking over my shoulder.

An ideal match for my trailer, love the handle!

Works flawlessly! Super sturdy build that gives me instant peace of mind. Fits my 2-5/16" cargo trailer coupler perfectly, and the carrying handle is a huge plus.

Reed Franklin
super tough, good luck cutting through this.

Similar locks at local hardware stores go for easily double the price. This is a steal. The money I saved can go straight into my gas tank.

Bright colors alone scare off thieves.

Salt air at the marina usually ruins standard locks quickly. I've been using this for a few weeks now in the rain and humidity, and there's zero rust or corrosion so far.

Pierce Morgan
Fits my coupler perfectly with zero movement.

Got this mainly for my jet ski trailer. It's always around water or damp docks, and my old locks used to rust shut fast. This one has those waterproof orange plugs, and after a month of use, there's zero rust. Super dependable.

Perfect for farm trailers left outside overnight

As a farmer, I have a few large cargo trailers parked out in the open. I used to worry about them constantly, but this lock gives me peace of mind. It's heavy, the black coating feels premium, and it definitely doesn't feel cheap.

I
Ivan Cross
Awesome black and orange colors.

Trust me, if you buy this, you'll see why I'm raving about the quality. It's solid metal, weighs about 7 lbs, and has a handy orange handle with the brand logo. Love the black and orange contrast. Highly recommend to anyone looking for solid security.

Fits both my RV and flatbed trailer

The black body with the bright orange cap stands out big time! You can tell from a distance that the trailer is locked down, which acts as a great visual deterrent. Thieves won't even bother walking up to it.

Smooth keys hole and a really useful handle

Solid steel and heavy duty. There's no way anyone is just prying this off. The handle makes it super easy to carry over and install, and the key mechanism turns smoothly without catching.

H

Love the recessed keyhole design

Just line it up and lock it down. I really like that the keyhole is recessed instead of flat stops rain and winter freeze from messing it up. The included key cover makes opening it a breeze every time.

Holding up great in salty marina air.

I used to use a cheap U-lock that rattled constantly and rusted shut within two months. This box-style design is way smarter. It completely covers the coupler, leaving absolutely no room for a crowbar.

P
Parker Vaughn
Way cheaper than the store.

Took the camper to Yellowstone last week and stayed at a pitch black boondocking spot. So glad I put this lock on before the trip. It fits tight with zero wiggle. My family and I slept like babies knowing the trailer was secure.

K
Kane Barrett
Got robbed before, but this lock feels secure.

After losing my last cargo trailer to thieves, I decided to up my budget and get something legit. This lock did not disappoint. While no lock is 100% thief proof, this one feels incredibly rugged and secure.

F
Finn Ken
My friend wants one after seeing mine.

Great lock for the price, way cheaper than the famous name brands but just as tough. My buddy has one of those basic, lightweight hitch locks that looks like it could be cut with a hacksaw in two seconds. After seeing mine, he's already planning to swap his out for this one.

Anti-theft protection

The trailer hitch lock uses an advanced locking mechanism,with each lock core having a unique key for security. It effectively prevents thieves from breaking in with thin wire; it can only be unlocked with the original coupling key. It comes with 4 replaceable orange covers that can be swapped if damaged or scratched.

Very smart design, hard to cut or pry open.

Shoutout to the fast shipping arrived way earlier than expected! Just in time for our weekend camping trip. Packaging was pristine, and all accessories (4 keys, 4 orange caps) were included. Great buying experience.

Slept peacefully while camping in Yellowstone

Well packaged and came with 4 keys! That's so convenient my wife and I both get one, and we still have two backups at home. The orange dust plug is a nice touch to keep dirt and rainwater out of the cylinder.

FAQs About Heavy-Duty Trailer Coupler Lock - Fits 2" & 2-5/16" Couplers

Please measure the ​​inside diameter​​ of the coupler's latch mechanism (the hole where the hitch ball goes). If it measures approximately 2 inches or 2-5/16 inches, this lock will fit.

The ​​tough powder-coated finish​​ is specifically designed to defend against rust, corrosion, and harsh weather, making it ideal for long-term outdoor storage. The included ​​orange dust caps​​ also protect the internal lock mechanism from moisture and dirt.

​Four keys​​ are included with each lock. This makes it easy to share access with family members, keep a spare in your truck, or have backups in case one is lost. Since each lock has a ​​unique key code​​, you cannot get a generic replacement. We recommend storing one key in a very safe, memorable place. If the key is indeed lost, please contact our customer service team to get a solution.
