Replacing Window Spring Balancers

Question

Hello -
I am looking to recommendations to replace these on 2 windows in my house.
The small window one is marked 26 4 DN Caldwell. The Metal part is 27 inches long.
The larger window is marked 32 9 BN Caldwell. The Medal part is 33 inches long.
I appreciate the advice.

Thanks for reaching out! Your window balances can be replaced with either the Series 380 or the S385 Channel Balance. To determine the correct series, you'll need to measure the depth of your bottom shoe.

Comparison of the S378, S380 and S385 balance shoes.

For the 27" balance you can likely use the 2640 stamp (supports ). You'll need to confirm the sash weight for the 32 9 stamp, as this does not cross-reference with the stamps on our 33" balances. It may be a good idea to check the sash weight for the 27" balance as well.

There is a chart below the product description of the balances that lists the weight range each stamp option can support.
