Awning window operator- sill mounted plate

Question

As you can see this operator has a 21"span. I'm confident a smaller unit will work. I think the key factor is the sill mounted plate. I've been known to be wrong.???? What do you think? David

Hello! Your operator appears to be a dead ringer for our 39-083, which also has a 21" span. The mounting plate appears to be the same but look it over and let me know if you had any questions.
