left hinge casement window needs new crank/handle gear. #80810 is stamped on arm
The window opens just fine but needs to be puched close from the outside while the handle is turned from the inside and locked

Hello, thank you for posting,

Unfortunately we are not able to cross reference the number provided. To further review, we will need to see the window open where we can view the base and arm(s) of the operator. From there we can get a clearer idea of the overall style needed. Thank you!

The home was built in 1990 and a number of cranks are stripped in the same way and will need replacement. Left hinge and right hinge. The photo is for a 30x34 approx window size

Thank you,

Please review the style and dimensions of the 39-031 and 39-032 or the 39-155 and 39-156 operators. The main difference is the length of the short link arm. Compare to your originals to confirm a good fit!

Also see the 39-107 cover and 39-114L handle. Let us know if you have any additional questions!
