replacement window balance 28"

A home owner from Ridgecrest, CA says:
I need three window balances for single hung dual pane metal frame windows manufactured around 1987. The metal channel is 28" long. The spring is 14" long. Pictures are attached. I don't know the manufacturer of the windows.

Thanks for posting! Before I can recommend any balances, I just need a bit more information.

First, we will need to see close-up pictures of the two nylon attachments at either end of the balance. This will determine what Series you will need. We will also need to know the length of the bottom shoe, which is a vital measurement.

Finally, we will need to know if there are any stamps or markings on your channel. If there aren't, we will have to know the weight of your sash in pounds.

I only have one balance with me and it only has one nylon attachment. Not sure what you mean by "bottom shoe.". The channel is stamped "2730" and what looks like "BSI"

Thank you for the pictures! The bottom shoe is the plastic attachment you have in the upper right hand picture. Please refer to the following chart to identify your bottom shoe.

Yes, my attachment has wings. It appears to be #15-004, 1 3/32"

Thank you. Unfortunately, we won't be able to accurately Identify the balance Series without seeing the top attachment. Were there any broken pieces left over? Even seeing a fraction of what you once had may help. Also, perhaps there is another balance in that window that is whole.
A home owner from Ridgecrest, CA says:
OK, now I have the other side balance, pictures attached.

I think that should be all the information we need! Please take a look at our S350-28 with a 2730 stamp option.
