Can Curt Flex Air 5th Wheel Pin Box Work With PullRite Single Point Attachment 20K Super Lite #2600

Published 09/21/2023

Question:

I just bought the Curt Flex Air pinbox for my 5th wheeler. I am using the Pullright single point hitch. An adapter over the king pin turns it into a ball to fit into the cup at the top of the Pullrite hitch. Sort of upside down from the Anderson hitch system. Can I use the pinbox this way with the hitch? Every question I see on the subject refers to the Pullright SuperGlide. Thanks.

The Curt Flex Air 5th Wheel Pin Box # LC328492 can be used with the PullRite Single Point Attachment 20K Super Lite (#2600) but it will require an adapter. The Flex Air uses the same pivoting jaw style you find on a Rota-Flex pin box so you need to use the PullRite Pin Box Rubber Isolator part #4446 to keep the king pin from working it's way out of the adapter.
