Hey there, Thanks for reaching out! The coil balance shoe you are searching for is the 15-180 Coil Balance Shoe. The compatible support is the 15-181 Double Support Detent Clip, which is used along with the 15-182 Coil Bushing. If you are looking to replace the coils springs, this shoe is compatible with the Series 190 Coil Balance, which is secured to the shoe using the 33-073 #8 x 1/2" Truss Head screw. To determine the spring strength needed for your window, you'll need to double check the coil spring for any stamps/markings. If there are none, you'll need to obtain the exact sash weight. Then you'll you'll need to take that number and divide it by the number of coils in the window. (For example, if your window ends up weighing 12lbs, you'd need (2) 6lb coils, one for each side of the window. So you would need the S190-640.) |
