Simonton Tilt Single Hung

Question

I have a tilt single-hung window with V-grooved IG units. The Sash weighs 29 1/2 pounds. It has an unusual triple-balance assembly with three individual coil supports connecting to the the T-bar tilt shoe. Only the bottom coil spring has a number 9 on it and the sash weighs 29 1/2 pounds. If I order your triple balance support the mounting holes will not line up. Can I place your balance springs in the old support with a new shoe? Let me know, thanks!

Hello, thank you for posting,

Please review the 15-199 pivot shoe that is compatible with the 1/2" Series 160 coil springs.

You could reuse your original supports, but the new triple support 15-150T only uses one installation hole.

If you want to stick to your three coil set up, you could use (2) S160-5 coils and (1) S160-3 coil on each side of the window.

If you want to switch to two coils, you could use (2) S160-7 coil springs on both sides of the window using the 15-150D double support.

As long as you are within a pound of the total weight, the sash should be supported.

Let me know what you think!
