Thanks for contacting SWISCO. I think we can help you replace your old balances but I'll need a little more information. First of all, it is very unlikely this is a Series 800 balance as it looks like the metal channel is 1/2" or 9/16" in width, while our Series 800 balances have a width of 3/8". Do the other balances you need to replace have more than one attachment at the ends of the metal channel? If so, could you take a picture of the other attachment? This is vital for helping us identify the kind of balance you need. Yes, if the balances don't work for two windows, you will need 4 balances. Finally, are there any stamps imprinted upon the balances? If so, please send us a picture. It is best to weigh your window sash so we know how much weight your balances need to support; but any stamp number will also give us a clue to the weight range. Thanks. |
