window operators

A home owner from USA says:
I would like to replace these casement operators (see attached photos)

I have six 24" wide windows that require a left and a right operator, for a total of six operators. The operators I have chosen are 3 EA 39-028E and 3 EA 39-027E

Two 16" window operator which requires a left and right operator, for a total of two operators. The operators I have chosen are 1 EA 39-254E and 39-255E

Also, I would require 8 handles, 39-114L and 8 ea Track 39-520.
Can you please confirm that these parts are compatible and will work with my application (See attached photos)

Thank You
Dan

Hey, Dan. I'm afraid that I cannot confirm if these operators can work for you. Your old hardware is just too old, so any substitute you choose is going to be a gamble. Even if the parts you picked out do end up working, it will likely require significant alteration to the sill and sill cover to accommodate the newer style bases. I'm sorry that we cannot give a more definitive answer.
