Spiral balance help
I had questions regarding my spiral balance. I believe it’s 18 inches, 5/8 with orange tip. I do not see how it was hooked in to the sash since both spiral balances were already hanging loose. Also the little plastic tabs on the sides at the top and bottom. I’d like to know what they ar ... (cont.)

3/8 Twist Spring Balances for Non-Tilt single-hung aluminum windows circa 1965
Hi. I need to replace balances in a house full of windows, but they are old enough (house built in 1965) so that exact replacements are probably not available. Attached are three pics. I may need the clips, too, and perhaps a twister to charge them once installed. I'm a little worried about the scre ... (cont.)

Which bracket to use?
I know I need a S500-18 spiral balance with a red tip. I'm now wondering which bracket to use with it? The existing bracket is 3/8" wide and 3 1/2" long. I think the closest thing to it is the 17-012 bracket. Original balances are 70 to 80 years old. Glad I could find a supplier because there a ... (cont.)
