Probably the heaviest well built trailer hitch lock we’ve ever owned We found the “Vehiclex Heavy-Duty Trailer Coupler Lock – 2-5/16-Inch Compatibility, Carbon Steel Anti-Theft Lock with Weatherproof Canopy and Dual-Layer Protective Coating (Black)” probably the heaviest well built trailer hitch lock we’ve ever owned. It came with 3 keys and instructions. We liked the high-strength structural steel casing of the lock, the ease of installing it, how firm it was on the hitch, and it is sure to deter theft. We’ve owned other trailer hitch locks that would be easily broken off with a hammer. This hitch lock would take a lot of abuse before it would be broken off. You get what you pay for and even though this lock is up there in price, we feel our other investments are being protected.

Good security This lock provides good security for trailers. I can feel much more confident with this attached knowing that it will be much harder for my trailer to drive away. It forms a tight connection with a lock that seems difficult to break.

Heavy duty!!! Wow! I don’t think a thief is easily gonna get past this thing. It is heavy, so be prepared for that. The way the locking mechanism is made, it seems almost impossible to break into

Pretty near perfect… I can’t imagine a more solid, easy-to-use trailer lock. Thiefs will have better success welding a new tongue on your trailer than getting this thing off. Comes with three keys. Solidly coated to control rust.

Dense materials, simple setup, good waterproofing Dense materials, simple setup, good waterproofing:This product is very dense and feels heavy and solid while handling, despite a relatively compact frame. The product is very easy to set up and the triple key set gives me good peace of mind since I can keep a couple spares at home if I ever need them. The unit is primarily made of steel, but the exterior powder coating does do a great job preventing rust, even when left outside for longer periods of time in rainy weather. The security this item is also a big step up, since it’d be pretty difficult to get through this lock without specialized tools (or one of the keys).Overall, this is a good product and I would recommend.

Good Design I am pleased with this lock. It has a good weight to it and feels solid. The finish is nice and looks good. I am using this on one of my enclosed trailers and it was simple to install. The lock mechanism feels good, I did oil it as I always do. I feel like the design of lock is a good deterrent. I say deterrent as a thief can steal anything and no lock is 100% secure. This lock will make a thief move on to a easier target, that is my thinking.I am pleased with it and I will get a couple more for my other trailers. 5 STARS

This thing is BUILT! This is definitely one monster of a lock, with an impressive weight coverage. The weight for me makes it a tad bit awkward, but it’s well worth it. The manufacturer does a repeated reminder to make sure that your coupler type and size matches. This lock is not only anti-theft but is also anti-drill meaning you better not loose the keys !!! At first the key was a little on the tricky side but afterwards it was fine. This lock has a lot of great specifications you can find on their site, for me when reading a review I want to know one thing, does it work. Yes, most definitely this lock works. No one is going anywhere without a key including you so again make sure you do not loose the keys.

Very Heavy Duty This is probably the heaviest trailer lock I’ve ever seen. I have no doubt it will protect and deter thieves from stealing my trailer. It was easy to put on and comes with multiple keys. I like that it has an awning like design to protect the lock from the elements as well. This lock may be more pricey, but I promise you can immediately see the difference in quality.

This canopy shields the lock from rain, snow, and dirt, ensuring that the locking mechanism remains free of debris and stays functional for years. It’s a small touch, but it adds so much value, especially if you plan on leaving your trailer exposed to the elements.4. Easy to Use: The lock is straightforward to install. Simply attach it to the coupler, lock it in place, and you’re done. The key mechanism is smooth, and the lock engages securely without any hassle.5.

The Fortress of trailer locks! These new round solid steel lock housings are the latest rage in trailer security. There is a huge leap in effective security when comparing this to the cheap “U-bar” from Walmart. It would take a long time to defeat this lock. Expect the theives to pass on your trailer!

Giant tank of a lock This is a heavy duty beast. I don’t think you can ask for any anymore. It has a good solid lock that operates smoothly with the dimple keys that are a little bit harder to pick than a normal lock. He has excellent shielding and is just very heavy a big chunk of metal. I don’t think anybody is going to be encouraged to try to brute force this thing it is much stronger than what you will be protecting. And extra shielding from the normal model.This offers a nice additional layer of security. And I see no obvious flaws in the design.
