Dimensions of Replacement Swivel Collar for Roadmaster Tow Bars

Updated 04/17/2023 | Published 04/16/2023

Question:

Im looking for the dimensions of this adapter to make sure it will work with the tow bar and base plates that I have. Specifically the diameter of the through hole for the pin that mounts these to the base plates as well as the width of that part, and the distance between and diameter of the two bolt holes that mount these adapters to the tow bar.

In regards to the Replacement Swivel Collar for Roadmaster Tow Bars part # RM-9200-6, the diameter of the pin used to secure the collar to the base plate kit is 3/4" diameter and the width of the collar here it attaches to the base plate kit is 2-1/8". The distance between the two tabs which attach to the tow bar end are 1-9/16". I went out to our warehouse to measure these for you.

I have attached a photo below of these dimensions as well.
