Channel Balance Replacement




Thanks for posting. This looks like either an S351-29 or S390-29 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe, or the heel-to-toe measurement. See below for reference. Compare both balances with your old hardware to see what matches best.

You then have to choose a stamp option, which designates the strength of the balance. Look for a stamp on the metal channel that indicates this. If there is none, or you are uncertain, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option under the product description on either the S351-29 or S390-29 shop pages.
