Great buy!

Works well as I have a 3” wide tongue so the 31/2 “ shaft works well. These are hard to find. Fits nice and secure on tongue and made by master lock.

Works as expected...
I purchased a new equipment trailer with a bulldog collar lock style tongue, so I needed something long, and slender enough to fit through the safety pin hole when the trailer is not in use. This works great, in combination with the coupler lock, and the wheel lock, I feel like my trailer is pretty secure. I will be buying a couple more for my other trailers since they are adjustable.

Not Rekeyable
Called customer support and they confirmed that this lock and the 1469DAT are not rekeyable. I recommended to them to make a keyed alike set in the future.

Visual Deterrent Only
I utilize this with the knowledge that it is a visual deterrent only. A pro thief will snap this off in 5 seconds with the proper tool. For driving around town where you are not away from the trailer very long it is ok. For overnight unattended parking it is useless.

Poor quality
Used only once. It was difficult to insert key and lock. Had to cut it off to un hitch my truck after one use.
