Hello,

Your existing casement operator appears to be an older version of our 39-172. The opposite handed version is part 39-171. Take a look at the dimensions and compare them to your existing hardware to confirm that this is the right replacement.

There are two different types of compatible crank handles for these operators. They are our non-folding crank handle 39-114L and our folding handle, part 39-205. The compatible Snap-Stud Brackets are part 39-546 and the opposite handed version, part 39-545.
