barker 21349 barker RV round foot plate assembly

Barker 21349 foot plate and the measurements are 5.75 inches outside diameter. And .525 inches inside diameter hole these plates come with a bolt and lock washer. The plate does have .665 inch offset from mounting surface to bottom of plate. They are steel and have been galvanized so they are silver in color. I’m unsure of the bolt size it is most likely a fine thread 12mm or a 1/2-28.

Please feel free to message me with any questions. Thanks for looking!
