Channel Balance ID

Thanks for posting. Please confirm that the length of the metal channel, not including the nylon attachments at either end, is 33". If so, please see our S351-33 or S390-33. The only difference between these two balance Series 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 pick your stamp option. Your stamp option of 3240 is for a window sash in the weight range of 23 through 28 lbs. Let us know if you have any questions.
