Dual Arm Crank window operator

Question

I'm looking for a dual arm crank window operator. I have a Truth,(30895A) window operator which is similar to Item 39-140. I ordered 39-140 it is marked as 16 inches. 39-140 is exactly what I need except the arms are only 12 inches in length not 16 inches. Do you have the item in 16 inches? In fact the arms on mine look to be 18 inches in lenght.

Thanks for posting. We classify these types of awning operators not by extended length, but by the 'wingspan' from hinge to hinge when the arms are retracted. If the 39-140 proved to be too short, consider the 39-083, which has a wingspan of 21-1/2". Measure your old operator's wingspan exactly as listed below to see if this matches what you need.
