Vintage steel window crank handle

A contractor from Dallas, TX says:
Hello. We are in need of about 100 of the crank handles circa 1930/1940's steel windows. we do not need the whole mechanism...just the arm (in black)

Wondering if you can help.

Thank you
Jillian

Thanks for posting, Jillian. If all you need is the handle, could you just confirm the size of the spline? That is, the diameter of the hole in the handle. Thanks!

from what my field superintendent told me, the Diameter is 1/4"...

Hmm... we don't have any handles with a handle in that size.

The thing is, your operators aren't made anymore. There is no direct replacement, though many customers have been able to get our 39-344 and 39-358 to work. They might work for you, as well, but as far as replacing the handle itself we would need a more precise measurement of the spline.

Hello.

The Following Crank Handle worked perfectly for our vintage windows. Glad we bought a few samples to test before spending the money on the entire mechanism. We would have spent way more money that need be.
