Standard Roadmaster base pins and connecting pins for their standard non-MX/MS adapters and tow bar components typically use a 3/4-inch diameter pin (or a standard 5/8-inch pin depending on standard receiver configurations, though direct Roadmaster base connections rely on 3/4" pins).
If you can email us at info@hitchwe.com, and specify which specific part of the 025 adapter you are measuring or what brand of tow bar you are plugging into it, I can give you exact clearance and pin dimensions.
