What is Diameter of Coupler Lock Pin in Master Lock Hitch and Coupler Latch Lock Set # 2848DAT

Question:

right now Im just using a larger hair pin clip in my coupler like is used on a standard 5/8inch receiver retainer pin probably not the safest or the best approach and I need to verify how large a diameter hole my coupler latch actually has to see if this set of locks would work for my application. Im towing a 2007 Puma Palomino 25rs travel trailer with a 2 5/16inch ball and coupler. See this Atwood style:13k Atwood 2-5/16 13k Atwood 2-5/16 Atwood 2-5/16inch A-Frame Coupler - 13k with the so called unique thumb latch.
