Sash Dyad Crank

A quick learner from Massachusetts says:

I purchased the sash dyad crank 5" (39-187 and 39-188) in White. Everything fit perfect except the part of the arm that connects to the window is just a little to large which is stopping the windows from closing all the way. It is almost like it wont swing in. Your arms measure 5" but when I measured my old one the arm is only about 4 and 1/4". Do you have anything that will fit or any ideas on how I can make the adjustments to make the arms I purchased fit?

Thank you,

Hey, Tom. I'm afraid we don't have a version of these operators with that size arm. We have researched in the past but never had any luck. We do have two possible solutions, however. The first is to move the bracket to which the link arm attaches over until it is at the appropriate position. The other is to drill out the link arm on the old and new operator, then place the old link arm on the new operator with our 62-014 rivet.

Hi Tom,
I read your post and sadly I am going thru the same exact thing. My link arm is 4 inches from circle to circle and every single part I find online is 4.5 inches. Like you, I tried the 4.5 link arm and my window would not close. Did you ever find a solution to this?
thank you,

Hey, Janette. Sorry to hear you're having trouble. At this time, the only suggestion we have is swapping arms using the 62-014 rivet, like we mentioned above. Sorry we can't offer an easier solution!
