Which Capture Plate is Needed to Use Pullrite Hitch with Rota Flex Pin Box  

Published 08/10/2026

Question:

I ordered this Pullrite auto-slider and am a little confused. Do I need to purchase a capture plate and a king pin isolator for my Curt Rota-Flex pin box, or just the capture plate?

Hey Drew, this is a great question but to use your Pullrite Auto Slider part # PUL35RR with a Rota Flex pin box you would just need the correct capture plate part # PUL38RR which locks the hitch to the pin box and allows it to slide the hitch back as you make tight turns. What are you towing?

Alliance 35’ fifth wheel. Short bed F250, taking no chances with clearance and I refuse to have to get out and manually slide it when I need to make a tight turn or back into a campground. Thanks for the assist.
