Today, we're going to take a look at the Demco Hijacker Autoslide capture plates for the Trailair Rota-Flex Pin Boxes. Now, these capture plates will prevent your king pin from pivoting inside your Demco Hijacker Autoslide Fifth Wheel Trailer Hitch, and these are required for use with the Trailair Rota-Flex pin box, but they will also work with the Trailair Air Ride pin boxes. They are a fast, easy installation. Comes with a nice set of instructions on how to install them. Basically, these brackets will replace the capture plates that come standard on your hitch, and they secure with the existing hardware. These capture plates are actually taller and longer than the factory capture plates on your hitch, which allows the auto function of the hitch to operate without a delay.
These parts are made in the USA. But that should do it for the review on the Demco Hijacker Autoslide Capture Plates for the Trailair Rota-Flex Pin Boxes..

The stock guide plates will work. That being said, these help so much more! The are taller and longer. This guides and captures the kingpin better. By covering more of the king pin with these rails it allows the auto function of the hitch to operate without a delay. The delay in operation was something I experienced with the stock rails. That is what caused me to start searching for something better. Happy to have found these!

After a year and lots of towing miles later, they are still working great!
They fit perfectly on the Demco autoslide. They are quite a bit larger so they will contact the rigid part of the rotoflex pinbox.

These are still working perfectly. I have decided it is easier to take them loose every time I hook up, then snug them after hooking. Just the design of the autoslide mot the capture plates.
I don’t know why they don’t just build the hitch with these on them from the factory
tech support was awesome and I learned alot from them!
Thanks for having this hard to find product, it would have been nice if the salesman at the RV dealership would have known I needed to upgrade to the larger capture plates but your website was so helpful even providing a video that answered all my questions. Product was delivered faster than expected and was just what I needed. Thanks
This tightens the contact with the rota flex!
They look good. I'll be more frank on how they fit and work are after installation.
As always, fast shipping excellent service and a fair price.
bigger and longer then original capture plates. perfect fit.
Very helpful and quick delivery, reasonable price.
These look much more substantial than the original ones. I have not actually used them yet but believe they will work very well.
Arrived earlier than expected, good quality, well packed and in great condition. Sales was great, walked me through everything I would need and even verified information about my trail and tow weights. Great job guys
etrailer is always great to work with and their help with these capture plates for my pin box is yet another example of that. That said, like some of the other reviews that I read prior to purchasing these plates, I wonder why Demco doesn't just put these on from the factory. They are awesome and would work great with or without the flex pin box.
Thanks etrailer.

We’ll, here we are after a year and my Demco capture plate are still working perfectly. I highly recommend them.
Easy installation onto my Demco Hijacker Autoslide 18K and a much easier and safer looking connection to my Denali with the Trailair Rota-Flex Pin Box.

Satisfied. Makes connection much easier
Purchased the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Above Bed - 18,000 lbs
Item # DM8550034 for our Nissan Titan XD pro4x. After reading about 5th wheel pin boxes, I call to see if the factory capture plates would work for our new Keystone Cougar Pinbox. I called, spoke with Cailee V in customer service. Cailee was not 100% sure. She got my information, called Keystone to see how the pin boxes were set up. She followed back up with me the next day and advised I needed to purchase the capture plates for the roto-flex pin box. Order and they arrived in 2 days. Fit my hitch perfectly. Great Customer Service, thank you Cailee, great hitch/mounting bracket and capture plates.
Hitch arrived in excellent condition. I was a little disappointed at how long it took to arrive, but with the pandemic going on, I understand. This is an excellent hitch. It definitely requires a second set of hands to drop it into the puck mounting system in the truck. My wife and I picked our 5th wheel up this past Saturday and brought it home to get it cleaned up for our trip. Very smooth and very quiet. Much better than our last manual sliding hitch. The only negative from me is that I was missing 2 of the pins that hold the arms in the locked position. Supposed to be 4 and we only had 2.
everything works great , on the hitch head underneath there's a blue stopper for letting the head stop, they keep splitting and I have call Demco support on this problem and I have paid for a couple and they I sent me a couple at no charge. Have to change one about very two campground stop. Very upsetting do have to do this.If you have any questions please let me know .
I’m always impressed by etrailer product knowledge, service and prompt delivery. Not my first purchase nor my last.
Perfect with my replacement head. important with Trailair Flex Air 5th Wheel Pin Box equips my FW.
Fit perfectly into the Demco Hijacker Hitch.
Easy to install.
Shipping was extremely fast from etrailer / Mariah A. (thanks for that)
Truth be told, I have not used this yet, but have installed it on the hitch. While it was a little hard to take the old guides and install the new ones, I am sure these will work just fine. Both Demco and etrailer are standup companies.
Super fast shipping, overall a great product. Highly recommend!
Much bigger than the stock capture plates. Simple plug and play and easy to hook up to the Rotaflex kingpin on my trailer.
Better than what comes on the hitch. Very large gives piece of mind. Work great

Love the 5th wheel. I hope your deliveries have been improved. If you read my previous post, you’ll know that you cannot depend on the delivery dates that they give you. Don’t get in a hurry if you need it quickly, it won’t happen.
