Filter By - Locks

We will start off by showing you the actual locking mechanism itself. It has three positions. One obviously has a locked position. The second is the unlocked position which as you can see it goes in and out relatively freely. The middle position here is the ratchet position so you can go to unlock it and just ratchet it in like it is supposed to and then lock it. And that is pretty much the operation of it. Now we will show you its use on an actual coupler. There you have it, it is in the locked position and it is not going anywhere. To unlock, you put the key back in, and reverse the process. We will cover some of the advantages of this coupler lock. Obviously one thing is it guards against trailer tow away theft.
