Double coil spring balancer

Question

I need to get a replacement balancer for the left side as looking from inside house for a tilt out single hung verticle slider. Markings show 8 for the top spring housing no marking on the bottom housing that I could see. Guessing 10 or 12? Also need the spring hook tool recommended for this as well as any installation/replacement resources for this.

Hello, thank you for posting,

Your balance resembles the 15-087 pivot housing that is compatible with the Series 180 coil springs. Please review the dimensions below to confirm a good fit!

Detail of 15-087

For a double setup, you will need the 15-086 housing and the S180-08 spring for the (8) stamp. Since the bottom pivot housing does not have a number marking, can you provide the weight of the window sash? The sash will need to be removed and placed on a bathroom scale.

Also see the 16-024 mounting bracket. This balance does not use a specific tool for installation. Take a look at the diagram below for more information. If there is no cutout in the window to take out the balance assembly also see the video related on the page for the "cutout method".
