I am looking to replace the cranks on a weathershield casement window. It has a left and a right side. The numbers I found on it were 3581R and 3581L.

Hi there!
Start by taking a look at our 39-013 & 39-014or39-027E & 39-028E operators. Carefully look over the dimensions for each and compare them to your original assembly to see which one matches up for what you need.
