Replacement Channel Balance // 2090 27 BSI

Thanks for posting. See our 350 or 391 Channel Balances. The only difference between the Series 351 and Series 390 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". Below are the dimensions of each respective shoe. Compare with your old balances and see what you think matches best.

To know which length balance to select, please measure the length of the metal channel (not including the nylon attachments)--this is likely 21" for your old balance, but it is best to confirm just to be safe. Once you have selected the right length, you must also select a stamp option. Your stamp code of 2090 is from an older rating system we no longer use. To know which stamp option to select, you must weigh your window sash. You can then match that precise weight with one of the weight ranges listed along each stamp option on the product page. If this weight does not fit any of our listed ranges just let us know.
