I own a 15 year old house. I do not have any information on the window manufacturer. There are not any numbers on the window nor the balance itself. It is a coil balance yet I will gladly do a spiral balance if necessary The window is a double-hung with muntin bars inside of the double pained glass.
The lower window itself; window only; size is 31.5" length by 33" wide. The total window measurements are 63.5 high and 34" in width. I can weigh the bottom window if needed. It is double paneled glass and most likely weighs in the 20lb range.
I have attached a picture of the broken balance. I was given your company name by a friend and I sincerely appreciate any help you can give me!
