Good morning,

Left hand window crank mechanism needed. The teeth broke off of the base of the "swing arm". Enclosed is a pic of a similar window, as well as the part I removed. Only identifying markings was the # stamped in the 1st pic.

Thanks

Sean

Hi Sean,

Take a look and compare the specifications of the 39-175 and 39-176 Pella casement operators to yours. Please note that these use the 39-109B handle. We did carry the cover for these operators at one time but, unfortunately, it has since been discontinued. Thanks for posting.
