Master Lock 2847DAT Adjustable Stainless Steel Trailer Coupler Latch Lock 9/16 in. to 2-3/4 in. Long

The photo on the Website is deceiving. I was looking for a snowmobile trailer coupler lock. The diameter of the pin is smaller than a pencil. I would not trust this lock to secure a $15,000 snowmobile and a $5,000 covered 7x12 trailer.

Does the job! Didn't have any problems

Cause it's what I ordered

worked great great price

Master Lock quality is good. Works as it should. Everything is just overpriced now a days.

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

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.

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.

Seems like a high quality item and does it's simple job well. The only thing I wish was different is that the lock cylinder stays in whichever position you turn it to. Other locks I have you must turn to unlock and pull the two pieces apart at the same time. This means you can just slide the lock back together to lock it. This lock you have to use the key to lock it

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.
