Hopper window operator.

I'm afraid I don't recognize what you have from these images. Can you show me a picture of the base of the operator, as well? That's just as important as the arms. Thank you!

The base and arm configuration for the 39-083 is too different. I don't think that will work. You may instead want to consider our 39-312. This has the same kind of base and the arms are similar, but the sliders at the end of each arm are slightly different than yours. For one thing, ours are plastic instead of metal. The overall shape is also slightly different, but it may be close enough. Look it over and let me know what you think.

That's great to hear! Thank you so much for your kind words, they mean a lot to us. You know where to find us if you need anything else.
