seeking a stronger casement operator

Question

Dear Swisco,

We have a school with casement windows. I'm looking for a stronger operator.
It looks like the 39-001/002 and the 39-044/045 would both fit my windows.

Which one is stronger inside? I'm looking for something that can stand up to a 12-year old.

Thanks for posting! Neither operator is really stronger than the other. They both work equally well. The main difference is merely the style.
