Window operator inquery

Question

Hello!

I am looking for a replacement of this window operator and I've attached a picture with measurements (approximate).

Markings: on the straight arm, it has 41012 and on the other arm it has 31876.

I wonder if you could help to determine the right part.

Thank you!
Regards,
Xiaolin

Hi there!

Thanks for reaching out to us. This operator reminds me of the 39-253RB which uses the 39-529 track slider (sold separately). We recommend you measure as shown below to confirm a good fit.

If your old cover is built into the operator base and can't be removed, see the 39-452 for a new one.
