Two, faulty Constant Spring balance assemblies




Hi there!
Thank you for reaching out to us. We don't sell a 1:1 match for this coil balance assembly. However, take a look at the 17/32" thick and 1-1/4" wide pivot shoe as a potential alternative. The 1/2" Series 160 and 3/8" Series 165 are the compatible springs. You will also have to divide the precise sash weight by the total number of springs in the window to determine the proper spring weights. Review the specifications and see how they compare with yours.
Please let us know if you have any questions!





For 28-pounds of support on each side of the window, you could use two S160-09 9-pound springs, one S160-04 4.5-pound spring, and one S160-05 5.5-pound spring per side. This would total 56 pounds of overall support. For a new compatible quad support, see the 15-150Q.
I'm here if you have any further questions!
