Jalousie window operator for glass block window

A home owner from USA says:
I'm looking for a very small Jalousie operator for my glass block window.There are four mounting screws. One set is 4 3/4" apart, the others are 3 7/8' apart. The small terminal arm is 1 7/8' from end to end or 1 3/16" from center of rivet to center of hole. The interior arm is 2" from the center of the interior rivet to the center of the rivet where the other arm is attached.It is white and has a "T" type handle. I don't see anything this small on your website. Can you help me?

Thanks for posting. I would suggest that you consider our 39-346 universal type operator. Try the shortest arm that comes with it. If that arm is too long for your window, then you will need to cut it down and drill the hole at the end of the arm.

If you don't think that will work, or if you're not sure, we may be able to still help but I will need more information. Specifically, I will need to see a few pictures of the operator removed from the window. The reason we need it removed is so that we can see the link and gear arms, which actually do the job of pushing the glass panes open. Thank you!
