This is printed on the balance. 20 2 EW CMC 10. I also am missing the metal clips that go inside the window frame trough

Hello,

We believe you can use our S385-21 channel balance with a bottom shoe depth of 1-3/32". If so, the spring weight for your (20 2) stamp would be our (2020) strength option for a sash weighing between 8-12 lbs.

Also, take a look at our 16-002 take-out clip. Thank you!
