window crank

Thanks for contacting us. My first thought is our 39-317 and 39-318 operators. These look very similar to the hardware in your pictures. However, it seems your link arm is offset slightly, while ours is not. I'm not sure what affect that will have, if any. Let me know what you think.

Thanks for the additional picture. Like Tom said, the 39-317 and 39-318 appear to be our best match, however there's no way to know whether the lack of an offset arm will make a big difference. You will need to use your best judgement. In a worst case scenario, you could possibly remove the old link arm by drilling it out, then installing it on the 39-317 and 39-318 with our 62-014 rivet.
