Milgard Casement Window Crank replacement

A contractor from Oakland, CA. says:
I am looking for a replacement Milgard casement window crank. I have Aluminum cranks that need to be replaced. There is a stamp on it that says TRUTH with I think a part number of 45240. Below the part number there is another number but that one varies from crank to crank some say 13, 14 & 17? In any event I have a 75 unit condo building that I am remodeling and need to replace many of the cranks. Can you provide a replacement?

We may be able to help. Before I recommend anything, can you tell me the diameter of the hole? Please be as precise as you can.

If it is 11/32", as I suspect it might be, then see our 39-205.

it is 11/32 as far as i can tell

When I look that one up I do not see an aluminum one. These windows are all aluminum including the cranks.

You can also consider our 39-114L handle, which also has an 11/32" diameter and is available in aluminum. The only difference is that it's not a folding handle like the 39-205 that Tom mentioned.
