Wright 07900 window operator

A handy person from Colorado says:
I have an operator that I'm trying to identify and replace. The windows were blown open beyond 180 degrees in the wind, and will not properly shut now.

It appears to be a Wright 07900. I'm wasn't sure where to measure from until I saw your web site. The measurements are taken from the ends of the arms, not the center of the pivot points. I'm not sure if the 07900 is made in different sizes, or this model dictates what size the arms are. There is also a top arm on the window, as noted in the photo labeled "Full size render" If you could let me know what parts I may need to remedy this, it would be greatly appreciated!

Hello! Please see our 39-387 and 39-388. These might be the operators you want. Carefully compare them to your hardware to confirm. If you also need the hinge, see our 36-013-10.
