Window crank and cover

Thanks for writing in! Your casement window operator appears to be made by Pella. The handle can be replaced with the 39-109B 3/8" Handle for Pella. 

Unfortunately, we would not be able to supply you with the replacement for the cover. You may be able to contact a local Pella dealer to see if they are able to supply you with the replacement but I cannot make any guarantees.

Take a look to see if this handle would work as a replacement.
