I can't be sure what balance it is you have. The stamp is just an indicator of strength. I see you were looking at our S385-27. Is that the part you have? If so, then for a 30 pound sash I'd recommend the 2650 option. I highly recommend weighing your sash on a scale to confirm the exact weight, however. There is a chart on the S385-27 store page that lists every option and how much weight each can support.
As for the take out clip, see our 16-002. |
