K&K Operator

Thanks for writing in. It's a bit difficult for me to tell what your measurements are from these photos, but start by looking at the 39-155. Compare the dimensions listed with your old operator and see if this is what you need.

Thanks for the measurements. It's a good thing you confirmed them, because it looks like you need our 39-031 & 39-032 Operators instead. These are very similar to the 39-155 & 39-156, but the link arm is 4-7/16", just as with your old part. Take a look and see what you think. If you need a new cover and handle, see our 39-107 and 39-205.
