Window Balance Inquiry

Thanks for posting. Take a look at either our S351-22 or S390-22 Channel Balances. 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 what balance to select, you must choose a stamp option. Your stamp number '2190' comes from an old rating system we no longer use. To know which stamp option to select, the best thing to do is to weigh your window sash. You can match that precise weight with one of the stamp options listed on the product page. Let us know if you have any questions.
