Caldwell Window Balance

Hi Chris. This is either a S351-28 or S390-28 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe. The Series 351 bottom nylon shoe has a depth of 1", whereas the Series 390 bottom nylon shoe has a depth of 1-1/8". Compare with your old balances and see what you think matches best.

Once you know which balance to select, you will need to choose a stamp option. Your stamp code of 27 3 conforms to our stamp option of 2730. 

Awesome, sounds good to me! Thank you very much for your order, it's very important to us. Please let us know how it works out or if you had any other questions. We're always here to help.
