Window balance coul

Question

I need window balance coil replacements. The only marking I see is a '5'.  5lb I guess?  Can you help me with the parts I need?

Thanks for posting. This looks like the 15-177 Pivot Shoe, which works with Series 152 Coil Balance springs sold separately. For a spring stamped '5', use an S152-5 5 pound spring. If your old coil spring housing is undamaged you can reuse it; otherwise, see the newer-style 15-143, 15-144 and 15-145. These components 'sandwich' around the coil. Let me know if you have questions.
