Window balance question

I am looking to replace the channel balances on 9 identical non-tilt windows and would like to know, what determines the 'series' of channel balance to use? My balances are of the 1/2" (9/16") variety, are 29" long, and look to have the 15-003 shoe and 19-002 guide.

Thank you for your help and time.

Regards,
Ken R

A Series is determined by the nylon attachments, as you've rightly guessed. We could custom make a balance with a 19-002 top and 15-003 bottom, but I would double check your shoe, though. 15-003 is not all that common.

It would be more likely that you have a 15-001 or 15-002. The Series 351 uses the 15-002 while the Series 390 uses the 15-001. Please carefully compare their dimensions to your own hardware and see which is a better match.

Thank you for your reply. I have trippled checked the bottom shoe measurements and mine is the 15-003. Now I'm starting to wonder if the windows were ever built properly. I have pulled the sashes on 9 of the 5 windows and only 1 channel balance is in working order. Seems most top sash guides are also broken. I take it the top sash guide and balance tops need to match, correct?

Yes, I think pictures at this stage would be best. Please show us a top sash guide (as undamaged as possible) and the nylon attachments of your balance, both top and bottom. Thanks!

The sash guide is 7/8" wide by 27/32" deep by 1.5" long - screw hole is 15/16" from top. The top shoe is 1/2" wide by 11/16 deep by 1.25" long. The bottom shoe is 1/2" wide by 1-3/16" deep by 1-1/16" long.

Thank you for getting back to us! Our 18-138 top sash guide is longer than yours, but that shouldn't matter. What matters is the width that fits in sash, which is 3/4", and the screw hole placement, which is 1".

If you're confident you have a 15-003 shoe, then we can custom make your balance for you. I'm going to email you a custom order link and price quote that you can use to place an order on our website. Please let us know if you have any questions!

Thank you for help and suggestions. I have ordered 18 of both the channel balances and top sash guides, and look forward to having rejuvinated/operating windows. Ken
