63228 Gorilla Guard Universal Trailer Coupler Lock, Storage Security Lock Fits Most 2 Inch Trailer Couplers, Heavy-Duty Steel, Black

This device is great. It fits very well over my 2" coupler. and once locked has very little play. It is heavy which lead me to believe that it is well constructed of dense metal. As most people have stated, if someone really wants your stuff, they can get it with sheer determination. I figure the right kind of lock is a deterrent to 95% of the yahoos who would take a quick swing at getting my utility trailer. I had another one that had a shaped bar that straddled the top of the coupler. It was eventually lost, but I never did like the amount of play it had even when fitted as tight as I could get it. Also I always imagined that one or two good blows with a sledge hammer would have snapped it off. Because this one utilizes the common flange around the coupler, it would appear to draw on its strength to resist being pounded off. I think even if a grinder were applied to it, it would take a long time to effectively cut through enough of it to remove it. I also double up by using a special high-quality stainless bolt lock designed for the lever that locks the coupler to the hitch. So the SOB that tries to get my trailer is going to need all the determination and time he can muster. Yeah the lock is awkwardly keyed on the bottom, but it's a small price to pay for confident security, Buy it.

Purchased for trailer, fors exactly as described, easy to install & remove, very satisfied.

Highly recommend. Great quality lock that would take someone all day to try to get lock off and they probably still won't get it off

Chose this to secure our new aluminum garden trailer. Also had a lock to secure the chains back around the tongue so the chains could not be used to just haul the thing off. The first and only night it was left outside a serious attempt to steal the trailer was made. It was parked in the driveway of a seemingly well lit safe neighborhood. The trailer has deep tool marks between the lock and the rounded area that the ball goes up into and tool marks behind the same rounded area where they tried to pry it off. It is stronger than the metal of the trailer and seemed to reinforce the flanges it slides over. The lever that would usually lock the trailer on to the ball was beaten up, loosened and bent. A hammer was also used to the top of the ball area. The lock held up, the Thieves gave up and I still have my trailer. Don't think I would be saying that if I had gotten the ball/insert type lock. This one fit perfectly on the flanges of the 2" tongue. Easy on. With the deep damage done to the metal of the trailer I would expect some damage to the lock. Well, there was barely a scuff. I can highly recommend this lock. I can only say thank you for protecting my small but important trailer. Worth every penny.

It fits a little sloppy on my 5 Star boat trailer I bought the 2in. for a 2in. ball hitch.

Works great

I had been using a coupler lock that was part of a set. However, I always felt that it was cheap and would not stand up very well to any attempt to remove it. This lock is much more sturdy and when locked in place, does not appear that it would be easy to just pry out. There are similar locks that sell for a much higher price. This one is similar, and I thought it would provide a good improvement in security for a very reasonable price. Are there better locks out there? Yes. Are there ones that cost more that do not provide as good a security as this one? Yes. However, this one has the combination of features and price that make it very attractive. It should discourage all but the most determined people with a lot of time to work at removing it. It is likely to send people looking for an easier target.

It wouldn't go on my trailer tongue because the flange was as wide and as heavy duty as this lock. Measure the flange on your trailer before your order. It's a solid lock. I hope I can find a bigger version.
