window balance replacements

Quick Learner
Hi, I have the attached window balances which keep breaking. the top black plastic piece or the middle white plastic piece snap/break either where the spring attaches or where the string attaches. I am unable to indentify the window brand, there is no marking whatsoever on any of the windows (I probably have 20 of these in the house) and no labels or stickers. I have searched every window in the hopes of finding the manufacturer to get replacement parts.

Hello,

Unfortunately, your old-style rod balances are no longer available but it looks like yours uses the same terminal clip at the end of the pulley to attach the balance to the pivot shoe as the Series 770 channel balance. If so, you can use them as replacements but you'll need to measure the length of an intact rod balance and weigh the sash to confirm the strength options for your replacements. There is a chart on the product page that explains how to choose your option based on the sash weight. Thanks for posting!
