I need a few pieces to help me get the windows fixed in a house we are getting ready to sell. Two sets of two springs each. Here is what I know:
Set 1: 30" long with no numbers printed on or stamped into the balancing rod. They are 1/2' wide. It is from a window that is a single pane 30' by 48'. I added pictures of the ends and have more here if there is a way to send them.
Set 2: 35" long with 34 3 IW CMC 7 printed on it. It is from a single pane 33" by 68" window. I am giving you the size because we can't weigh the windows, the scale is gone already.
Last thing we need is about two dozen 18-166 sash cams. These seem to bake and break a lot here.
I can give you the card information for the order.
Thank you for your help and for such a detailed website.
Mike

Hi, Mike. Thank you for reaching out to us. We'd be happy to help but I'm afraid I can't identify your balance from these photos. Would it be possible for us to see an unobscured view of an undamaged bottom fitting? |
Absolutely. If you need any other angle or anything, please let me know.
Feel free to call...
Regards,
Mike

Perfect! Thanks for getting back to me. Based on what you show in these photos, I would recommend our Series 380 or Series 385. Measure as shown in the photo below to see which one matches up the best. For the 34 3 stamped balance, you would need the 3430 spring strength option. If the 30" balance has no stamp, you would need to weigh your sash and refer to the chart under the product description on the S380 and S385 store pages to determine the appropriate spring strength option for your balance. I know you said your scale is gone but I'm afraid weighing the sash is the only way to find out what spring strength you'll need.
