Trying to replace my coil spring balancers.

Question

My window no longer stays open anymore. It just slams shut so I decided to troubleshoot.

I see a 9 engraved on the coil.

The bottom hook part of my coil balancers are broken it appears. This is for my single hung windows that tilt in.

Hello,

The pivot shoe you have is our 15-180 Coil Balance Shoe. Although, you'll still want to compare the dimensions below to be absolutely sure this is the right fit.

This shoe is compatible with the Series 190 Coil Balance Spring. For the coil spring marked with a 9, I suggest using the S190-640. You'll need to look at the other coil on the assembly to determine the replacement for that one.

The coil spring is secured to the shoe using the 33-073 screw and uses the 15-181 Double Support Detent Clip along with the 15-182 Balance Bushing.
