SWISCO - The Replacement Hardware Authority

double hung window balance

A home owner from massachusetts says:
Hi,
I have to replace the balances on two windows marked 30C BSI.
Attached pics. They look a lot like the Series 795. Will they fit? The window is 32" from top to bottom. Would I get the 30" or 31"?


One more thing, The balance shoe has a patent number 4810108.

Thanks for your help!

Thanks for posting, Alan! The Series 795 balance looks close, but lets get some more information before we go any further. First, what is the length of the metal channel itself? Do not count the plastic shoe in this measurement.

Speaking of that plastic shoe, though, what is its width from ear to ear?
A quick learner from Massachusetts says:
Right. The rail without the shoe is 30".
Also 1/2 inch deep and 1/2 inch width. The shoe as you can see is 1.24 " wide.

since this is marked "30C" would that mean I choose the "C" option when ordering?

Thanks,
Alan

Thanks for getting back to us, Alan. Yes, everything appears to match our S795-30. For the option, I would also go with the 30C.
