OP 057810 window crank

Hello,

Could you show us the entire operator that this handle connects to, including the arms that move the window sash in and out? That will help us determine your best replacement option. Thank you!

Great! Take a look at the single-arm and dual-arm Roto operators we've related for you and see how the dimensions compare to your original hardware. 

Both of these sets of operators work with our 39-114L and folding 39-205 handles but it looks like you'll need to replace the entire operator to repair the one using the handle form your original post since the worm gear that holds the handle to the base appears to have broken off. Thank you!
