Shorter arm lengths available for the 39-172 + 39-171

A quick learner from Clarence says:
I need the operator exactly like 39-172 in white, except the part of the operator that is shown in the illustration that is 5 inches long is only 4 inches on my operator. Is this available. Everything is identical to my operator except that last link that connects to the window.

Thank you for posting.

Take a look at the 39-317 and 39-318 casement window operators. This may be the type you need.
