Broken Coil Spring Pack.

Thanks for writing in. This looks like a 15-180 Pivot Shoe, which uses Series 190 Coil Balances. These components are sold separately. For the coil springs, you'll need to look for a stamp on the coil spring to determine what spring weight you need. If there is none, or you are uncertain, tell me the exact weight of the window sash these coil springs support, and I can work out what you need. For a new coil housing support, see the 15-186 and 15-182 parts, sold separately.
