Constant force balance replacement.
Thanks for contacting SWISCO. I think we can help you replace your coil springs; but first, could you show us the pivot shoe that they attach to? If you could take a picture of the shoe removed from the window and provide the width and thickness, that would be most helpful. The type of pivot shoe determines the coil spring you need. Thanks.
Thanks for getting back to us with some detailed photos. I notice that you have the old Series 140 Quick Tilt coil balance spring system that has been discontinued. We'd like for you to get back in touch with us with the weight of the sash, or spring weight numbers that may be stamped on the old springs or housings.
For your 9 lbs. springs, you will use S140-9. They come in left and right. The pivot shoe dimensions are 1-1/4" wide by 9/16" thick. I hope this helps. Let us know if you should need any further assistance.
I'm not sure I understand your question. Our S140-9 balance comes with everything shown in our store's pictures, including a pivot shoe and spring cover.
My pleasure! Thank you for your business and please let us know if you ever need anything else.
