Hello,

It sounds like you may need channel balances for your windows. If so, we should be able to help but the stamp codes do not identify the balance series you need. To get started, we'll need to see photos of an intact balance removed from the window. Please make sure to include both end fittings and the pulley clip. 

We'll also need to know the exact weight of the sash supported by the 2790 stamped balances since the stamp is from an outdated system. We'll be able to determine the spring calibration needed based on the sash weight. Thank you!
