Hi there. I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Demco Hijacker Autoslide Locking Plate for your MORryde Pin Boxes. Now, the way your Demco Hijacker Autoslide functions, you're going to have to prevent the king pin from rotating in the hitch in order for it to have the correct pressure in order to slide. So, we are going to need to isolate that movement at the king pin, and that's what this plate is gonna do. This is going to bolt on to your MORryde pin box, and you can see we do have this wedge here.
This is going to fill up your jaw channel, and so it's going to make sure that your pin box isn't going to be rotating at all, and then it will allow your Hijacker Autoslide to swing out as it needs to to make those tight turns for you. So, this is gonna be very easy to get mounted on to your pin boxes. They do include the hardware that you're gonna need as well as instructions with very detailed pictures to help you get it installed. So very, very easy to get installed, and it is gonna be really necessary for your Hijacker to function properly. This is a nice, durable carbide, corrosion-resistant powder-coat finish, so it is gonna hold up really well for you.
Nice solid construction. So, it is gonna do a really good job of ensuring that your Hijacker is functioning properly with your MORryde pin boxes. It is made here in the USA, so you can trust it is gonna be a good quality for you. Like I said, very easy to get bolted in place, and it's going to make sure that your autoslide is functioning. So, that completes our look for today.
Again, I'm Michael with etrailer.com. Thanks for watching..

Thanks for the feedback, Johnny. Glad to hear it was a perfect fit and everything lined up the way it should. That’s always what you want with a setup like this so you’re not fighting it during install. Demco makes some really solid gear, so it’s great to hear it worked out well for you. What kind of fifth wheel are you running it on?
