Broken window parts

A quick learner from 33837 says:
Old Castle is stamped on the window. I think I need P/N S385-29 (both sides) and definitely need the sash stops that screw on the window itself.

"28D" is stamped on the sash.
265-2 5E is also stamped on the sash hardware.

The nylon stops on the window are broken.

Thanks for your help with the part numbers.

Hello,

With this combination of attachments, you could have either an S380-29 or S385-29 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 2840 spring strength options for your replacement balances.

Thank you and let us know if you have any other questions or concerns.

Thanks so much. I placed the order for the channel balances and also I ordered (2) 18-180 sash guides which look like the correct ones.
