Double Coil Balance Spring

Question

Attached find pictures of a double hung window with Coil Balance Springs. This is one of the top Coil Balance Springs which broke. The Springs are numbered 7, the Double Detent Clip is broke on the top this can be seen in the pictures as you can see both of the springs broke and need to be replaced. The width of the springs is 15/32; in your parts catalog it seems to be an 180-7 Coil Balance Spring, the Double Detent I located in your catalog is a 15-181. I can reuse the Balance Bushings. I need to know it these are the parts I need to repair my window. If you need additional information please let me know. Thank you.

Sincerely,

Andy

Hello,

Your balance show looks like an older version of the 15-180, which uses the 1/2" wide S190 coil springs and the 15-181 double support that you mentioned. Take a look and see how the specifications shown on our product pages, as well as the parts shown under the related items section, compare to your original hardware. Thank you!
