If you are referring to the inside diameter of the socket head on the Replacement Manual Override Crank for Bulldog Powered-Drive Trailer Jack part # BD500203 then that is 1/2"diameter. The diameter of the handle portion is also 1/2". If this is not what you were referring to then please let me know and I would be glad to go take any other measurements you should need.

What would be the outer dimension I am wanting to replace the manual override I lost part number 85385 non available anymore. My power Jack is an Atwood 88320 3000lbs. A 1/2 inch socket fits in the hole over the shaft, I just need those two slots. Thank you!

@JulieP I went out to the warehouse and measured the outside diameter and what I got is 11/16". Is that going to work for you?

@KateF Thank you for the info, Yes it would fit, Original manual override tool is 13mm x 19mm which is pretty much 1/2 inch x 3/4. The slots opening on your end is not written, mine is 1/4 wide x 9/16 th deep.

@JulieP Thanks for letting me know Julie! I just ran out to the warehouse and it is right at 1/4" wide x 9/16" deep. Looks like it will work perfect for you. Beats buying a new jack!
