This looks like a Series 351 or Series 390 Channel Balance. The only difference between these two balance Series is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. We judge channel balance lengths by the length of the metal channel, so I would confirm the metal channel length of each set you need to get this right. Finally, we generally recommend you choose stamp options based off the old stamps on the balance. I see one of your balances has a stamp code of 3120. This stamp designates a balance that is meant to support a window sash in the weight range of 12 through 16 lbs; yet you say both sashes weigh 26.6 lbs. Did you ever have trouble keeping these windows open before the balances failed? In any event, I would highly recommend double-checking those sash weights, and please show us the stamp codes on both set of balances if you're uncertain. |

All the prices for the S351-26 and S390-26, as well as the S351-32 and S390-32, are listed on their respective shop pages, and shipping options and costs are listed when you input your zip code upon check out. Now, if you are saying the balances failed to really hold up the windows even if they hadn't broke, and if you are absolutely certain both windows weigh 26.6 lbs, then you might want to consider a stamp option of 2550 for the 26" balances (which supports a sash in the weight range of 25 through 28 lbs), and a stamp option of 3140 for the 32" balances (for a sash in the range of 23 through 28 llbs). I stress that you should be absolutely certain that the window sashes indeed weigh 26.6 lbs exactly before going this route, but these would be the proper stamp options for that sash weight. |
