I have old 1920s wooden sash windows that I'm replacing with new ones I'm building in my shop but I don't want to use the original weight and pulley system as the balancer. I'm not sure which balancer you sell that would be the appropriate balancer (and additional parts) for my need. Can you direct my efforts? The window is 32''x32''.

Thanks for choosing SWISCO for your hardware needs. We have a 5/8" Series 500 spiral balance that attaches to our 17-012 sash bracket. This has been used by wood manufacturer's for quite a while. The 17-012 bottom bracket is screwed on the bottom of the sash with a screw similar to our 33-073. The 5/8" tube balance would be screwed at the top of the window track with the 33-016 screw. The length of the balance is determined by the sash glass height. The top sash would be 1" taller than the glass height and the bottom sash would be 3" taller than the glass height. You would need to cut a groove out the sides of the sash by 5/8" X 5/8" to accept the balance tube. |
