METOWARE Trailer Coupler Lock Universal Adjustable Heavy-Duty Steel Trailer Hitch Lock, Anti Theft Trailer Ball Lock Towing Lock for Towing Trailer Security Fits 1-7/8",2”, 2-5/16" Coupler Yellow

These work great. Really good product for the price. I have them on all my trailers. They hold up to the elements well and I’ve never had issues with them freezing up during the Alaskan winters. I accidentally lost the keys to one and had to cut it off with a grinder wheel. Took me about 15 seconds to cut through it but there’s not many tongue locks out there that can withstand a grinder and certainly none for this price. I doubt a bolt cutter could make it through without serious effort. Having a big yellow lock on the front of your trailer is definitely a good deterrent.

I needed a way to secure my boat trailer during the summer when my pontoon boat was on the slip. This worked perfect.

Perfect for locking the hitch receiver on my old canned ham travel trailer. Very easy to use.

Great product for the price, and works on a size 2” ball. Only thing is that the lock system itself is not the greatest of qualities. Will hold back a theft opportunity, but one smack of a hammer loosens the lock. Overall, well worth the money; compared to the multi hundred dollar ones.

Looks and works great. Simple to install and does its job. Made to last. Bought a second one.

Definitely not heavy duty, but looks like it is. It should deter theft. Bright yellow, definitely noticeable.

Fitted without issue

Good product, keeps my trailer safe from theft
