Hello and thank you for writing in. Let's start off with your coil springs. Our S190-840 does look compatible to what you have and can carry a sash weight if eight pounds. Take a look and see if this looks like the correct spring. If you should also need to replace any of the accessories of the coil spring system, I placed a list of those items on this page for you to look over. Take a look and see if these match up to what you have. |
