Replacement Operator for Simonton Windows

Question

My Simonton windows manufactured around 2000 appear to take the Maxim Dual ARM Operator, Sill Mount. The current operator has the word "truth" engraved on it and the number 31858 on the window with the lock and the crank on the right side(when viewed from inside).

The 2 measurements are 4 7/8" and 4 15/16".

Thank you for contacting us. The 39-220 and 39-221 do look very similar, assuming the dimensions match up. I also can't make out if your operator has the same screw base as ours, but it may just be obscured by the window frame. As long as you have a screw base, and as long as the dimensions are the same, these would be a great choice.
