Hello,
I am in need of approximately 50 sash balancers for an apartment complex. The balance in the picture isn't broken, just removed for pictures. I don't see any markings on the balance. The dimensions appear to match your S140 series. Please advise.
Thank you,
Don
Hi Don. This is actually the 15-180 Pivot Shoe, which uses Series 190 Coil Balances. If you're replacing the coil springs you'll also need to select a spring weight, which indicates the strength of each individual spring. Look for a stamp on the spring to know what spring weight to select. If there is none, or you're unsure, give me the exact weight of the window sash these balances support, and I can work it out for you.
This coil balance system is modular, meaning you only have to replace the parts that are actually broken. But if you want new housing for the coils, see the 15-181 and 15-186 support components. Let me know if you have further questions.
