That is an odd stamp number.
Please remove the window sash and place it on a scale to get the window sash weight in pounds. Next, look up the weight on the following Balance Stamp/Weight Table:
*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. |

We can custom make a balance for you with a 2170 stamp option. Two balances with that stamp can carry a window sash weight range of 34 through 37 pounds. If that's what you want to do, then check out this Custom Channel Balance Request Form I've started for you based on your specifications and fill out the rest of the information. One of our representatives will get back to you with a price quote and an item to add to your cart.
