Demco SL Rail Measurements For 5th Wheel Hitch

Updated 07/06/2020 | Published 07/02/2020

Question:

I have an old RBW model UHS-85-7 5th wheel and it needs new rails. What are the width of the rails from the inside of the upper “plate” and what are the distances from locking pin hole to hole on the top?

Expert Reply:

The RBW hitch is not compatible with the Demco SL rails you referenced as they are designed specifically for fit with the Demco SL hitches like # DM6076SL-16K. The width will be 30-1/2 inches from side to side.
