Review of the Master Lock Trailer Coupler Lock


Today, on our trailer, we're going to be taking a look at the Master Lock Trailer Coupler Lock, for 1-7/8", 2", and 2-5/16" Ball Couplers. Part number ML389DAT. Now, with our heavyweight design, that's going to deter against trying to shatter it or bust this lock off of here, and since it's painted red and powder-coated, it's going to resist corrosion and rust, and it's going to be a great deterrent. When somebody sees that you've got this on there, they're not even going to mess with your trailer. It's going to have a wafer-style tumblers. They're going to resist picking and tampering, and it locks into position, and when you take the key out, you know it's secure. Now, we're looking here, at our trailer right here, even if we we're to lock this coupler on the top side from the collar, somebody could come in with a smaller trailer ball, and just slip your trailer on to it, and off they go with your trailer.

Now, with our Master Lock coupler installed, we would just slide it up into place, and we'll push it down, push it back until it's tight against the ball, against the coupler, and we'll lock it. That's not going anywhere. It's secure inside the tongue of the trailer, and you can't put another ball inside there to be able to run off with your trailer; so even if this was locked, it still wouldn't make a difference. This is not going to come out of here, and it's secure. That's going to do it for our look at the Master Lock Trailer Coupler Lock, for 1-7/8", 2", and 2-5/16" Ball Couplers.

Part number ML389DAT.
