215 Brownsville Rd- 2F window coils

Question

Hi,
I need help selecting the correct window coils for a property that I manage. Please see the attached pictures. One of the coils appears to have "DL" stamped on it and it can't find anything on the other coils. I need 4x coils total for the top and bottom hung windows. Please let me know if you need any other Info.
Thanks,
Sean

Hello,

Your exact pivot shoe was discontinued a while back, but the 15-177 works as a direct replacement. It also uses the same S152 coil springs. Since yours have no stamp numbers, you'll need to weigh the sash that the balances support, divided by the number of coil springs used on both sides to support it. That will tell you the strength options needed for your new coils. We also offer the 15-143, 15-144, and 15-145 support hardware for the coil springs. Thanks for posting!
