Window Dyad Crank

Question

Should have done this first. Arm labeled B looks to be too long, it hits window
frame when trying to close. Arm labeled A is longer, but that would probably only affect the amount of how far the window open, (not an issue).
Any help appreciated.
Thanks,
K

Hey there!

Thanks for reaching out to us. The 39-188 looks like a better match based on the style of the gear arm. However, the overall length of the link arm is 5". If yours doesn't match this, you'd have to either try the operator as is to see if it works regardless or swap the new and old operator arm. You'd have to drill out the new and old arm and use the 62-014B rivet. To install this rivet, you'll have to hammer it in; I recommend doing it over a metal plate if you have one. Take a look at the specifications and see what you think.
