Constant force balance
Hi there!
It looks like you have our 15-087 which holds the Series 180 coil balances. If you need a new mounting bracket, please see our 16-024. Remove your pivot shoe and compare our dimensions to yours to see if this matches up for what you need.
thank you
To determine the coil strength, you'll need to remove and weigh your sash and then divide the precise weight by the number of springs in the window.
For example, if you had four springs total (two on each side) and a 12 pound sash, you would want four 3 pound springs.
I hope that helps!
Thank you
You can do either, the decision is ultimately up to you. You say you have a total of 2 springs in your window, one for each side, correct? So, one 8 pound coil for each side would equal a 16 pound sash. If you do one 7 pound coil on each side, that would equal a 14 pound sash. It wont matter much if you're off by a pound. For the screw, please see our 33-072.
