SWISCO - The Replacement Hardware Authority

This is a casement window opener that lacks its crank

A home owner from San Diego California says:
So this is a window crank that does not have a handle, or else an opener that lacks its crank. Another window in the same house has a small removable crank. The opening is square, and that makes it difficult to measure. The part that inserts into the opening on the other window's small brass crank/handle is 1/4 inch, but this is definitely bigger, because that crank just rattles around in this opening. It's difficult to measure the interior of a receptable, what would you use, a pair of calipers? In any case, the dimension of the square end that inserts is somewhere between 3/8 of an inch and 5/16. Are there any standard sizes of these cranks?

Hey, just wanted to say that I identified the item on your website. Sorry, I should have been able to figure that out on my own without bothering you. I purchased "Wood Casement Crank Handle, Brass Finish 39-347".

Thanks

Thanks for posting! I'm glad you were able to find something, though you said you need something larger than a 1/4", while our 39-347 is 1/4" square. You might want to consider a new operator like our 39-268. Your operator could be an older model with a larger hole.

Ah, right you are. So that will be useful strictly as a replacement for the existing one. I had cognitive blindness there for a second. So you'd say they no longer make anything larger than 1/4 inch?

I'm afraid not. That's why I think it might be a good idea to just replace the operator itself. That way you can just mount it to the window without worrying about if it will fit or not.
