Bow window

Thanks for reaching out to us! I'm happy to identify the replacement parts you need but I'll need to see a photo of the hardware to confirm the correct replacements. Unfortunately, I would not be able to identify the hardware you need based on the information provided.

Are you able to provide photos of the hardware?

Thanks for the photos. Your window operator reminds me of the 39-329 LH Inverted Split Arm ROTO Operator used along with the 39-553 Roto Sash Bracket. To confirm that this is the right replacement for your existing operator, carefully review and compare the dimensions below.

The opposite handed version of this operator is the 39-330, likely used with the 39-554 Roto Sash Bracket for your application.

Both of these operators are compatible with the 39-232 Roto Folding Crank Handle.
