Today we’ll be taking a look at the Master Lock High security Kingpin Lick, part number ML387. As you can see it’s going to secure our fifth-wheel trailers, or semi-trailers and our RV trailers. It’s made out of a high-grade aluminum, it’s got a nice color red so we don’t lose it. It’s going to be resistant to bolt cutters. On this side you notice our locking components, it comes with two keys, nice master lock, and a nice easy handle for carrying. Now that we’ve gone over some of the features I’ll go ahead and show you how easy it is to install. First thing I want to do, I’m going to make sure that our tab here is in the unlock position, right there.
