Have two windows with broken coil spring balancers

Question

I need replacement coil spring balancers for two windows.  I am unable to find any identifying markings, serial numbers, weight ratings, etc.  Pictures are uploaded.  House is in a development in Southern New Jersey, built new in 2003.

Thanks for reaching out! This coil assembly is made using the 15-180 Coil Balance Shoe. I'm confident it is a match, but be sure to double check the dimensions.

The compatible pivot bar is the 26-040.

The compatible coil spring is the Series 190 Coil Balance, secured to the shoe using the 33-073 screw. To determine the correct replacement, you'll need to confirm the stamp/marking for the coil. If the balance does not have one or it is hard to find, you'll need to confirm the exact weight of the window sash.

The coil is anchored to the window track using the 15-186 Coil Balance Clip and 15-182 Balance Bushing.
