Hi,
For balance stamp options it's best to replace with the stamps found on the original balances if they worked properly.

S385-28
24 lbs sash, choose stamp 2740

S385-28
36 lbs sash, choose 2765 or 2770

This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
