Crank replacement, casement window

Greetings,
I have an older Anderson-type (not sure, no markings) casement window and the crank and arm assembly is not functioning. Could you please help ID this and direct me to the part I'd need to replace?

Thanks,
Mike

Hi Mike. See our 39-028E. Look it over and let us know what you think.

Yes, I'm confident this will work for you. The dimensions all seem to line up. I guess I could also throw out our 39-028, which has identical dimensions but just looks a bit different. I usually just recommend the 39-027E and 39-028E instead though, since they're more modern replacements.

Well it looks like it would work. Do you think so?

Great thanks... Do you feel I can reuse the handle/crank? I measured as close as possible with a caliper and I se it as 10/32" or 5/16, not 11/32" But it may not be that accurate of a measurement...

Oh yeah, you can definitely reuse the handle. The hole diameter should be 11/32". If you do end up needing new ones, you could use our 39-205 (folding) or 39-114L (not folding).
