Balance




Thanks for posting. This looks like a 15-180 Pivot Shoe, along with the 15-186 Balance Clip and 15-182 Bushing. This system works with Series 190 Coil Balances. If the window weighs exactly 15 pounds, no more, then you could use a pair of the S190-740 7 pound springs, for an overall weight support of 14 pounds. Being within 1 pound of the exact weight works just fine. We highly, highly recommend you weigh the sash on a scale to confirm the precise weight before proceeding. For a fastener, you might be able to use something like the 33-073, though this can depend on the window track itself. Take a look and let us know if you have questions.
