These will NOT fit Sears or Thompson sprinklers that have the aluminum impeller shaft. If you're purchasing this to replace the shaft in a Sears or Thompson sprinkler, check the length from the bottom flange to the tapped hole and compare with the picture above. If you need an impeller shaft for the Sears/Thompson sprinkler, check my other listings.
These impeller shafts are Made in USA - claims of "US Shipping" or "US Stock" are just another way of saying "Made in China". My photos are of the actual item, not an artist's rendering. And unlike my competitors, who flood ebay with cheap copies that may or may not fit, I actually own and use the sprinklers.
