I am looking to replace the existing casement operators from Silverline windows. The windows were manufactured about 2008.

Thanks for your post! The window operator is similar to the 39-329 LH and 39-330 RH Inverted Split Arm ROTO Operators. Both operators use the 39-232 Roto Folding Crank Handle.

The link arms attach to the window sash using 39-553 and 39-554 Roto Sash Brackets.
