We live in an old 1907 loft building that was converted from a warehouse. The windows did not stay up, so we replaced the channel balances with new ones. The windows stayed open for a day, but now they barely stay open.. We used the same stamping balances that was in the window...33" stamped 3240....it was a 390 series. We recently replaced one window with a 3250 hoping the new balance would be able to hold the weight better. After a few days, it has also started inching its way down again. It is better than the previous one, but not holding like it should. We are not sure what else to try and was wondering if you have any suggestions for us...a different balance or the same one that can hold heavier weight or adding something to the window.
Thank you,

Hello,
Sorry for the delay. I had to get someone to help me take the window out. My windows weigh roughly 41.5 lbs each. And yes, we replaced both channel balances when we took the originals out. If the stamping is too low (meaning the 3250 won't hold it), what our options? We need the 390 series.
Thank you,

Good morning,
Based on the thread above our building purchased channel balances, which was a fairly large order. They worked great at first, but are now having difficulty opening and some windows do not stay up. My sashes weigh 41.5 lbs as indicated above. I believe I purchased the 3290 as I was almost at the weight limit for the 3270. Do these need to be replaced ever 3-4 years? Should I go down to the 3270 (will I get more service life out of them)? Please advise.
Thank you,
GG
Sorry to hear you're having trouble. We actually don't sell any balance with a 3290 option. According to our records, you purchased four different strength balances: 42 balances with a 3275 option, 18 with a 3270 option, another 18 with the 3260 option, and 4 with a 3250 option.
Can you confirm which of these is the balance giving you issues?
Hello, my apologies. Several units ordered balances. I used the 3275 in my unit as I was close to the weight limit of 42 (again, my sashes weigh 41.5 lbs). Not sure why I wrote 3290.
Do these need to be replaced every 3-4 years? Should I use the 3270 or 3275? If I use the 3270, will I get more service life out of them?
If the sash weighs 41.5 pounds, then I would go with the 3270 option. This can support 39 through 42 pounds. Any stronger could cause problems. There is no benefit to using a balance that is stronger than what you need, and it can actually lead to the window working improperly. Typically, a balance would last 5-10 years depending on how often it is used.
