Hi! Our casement window (if inside facing the outside, the right side), was damaged due to wind, causing the hinge to break. Here is the information we could find:
Roto G2-STRKR-12
These are the measurements that we found ourselves (not listed on the parts)
9 3/4 inches attached to sill
7 inches on the window bottom
Arm is 5 1/4 inches (the part that connects sill and window)
"B" opening window
If you need any more info from us, please let us know!
Thank you!
Lia and Mason
