I need 4 right and 6 left cover and handle. (lost during construction)

Thanks for writing in! if the cover and handle can be removed from the operator, our 39-451 and 39-452 Encore Cover and Handle kits should work for your repairs. The other options are the 39-375 and 39-376 Encore folding kits. 

They're each available in an assortment of colors.
