Window balance system replacement

Your coil spring system is a little different than ours, but I am sure we can still help. With the way your coil spring hooks into your pivot shoe, our coil spring is actually screwed into the shoe. That said, have a look at our Series 152 coil spring and 15-177 coil balance shoe. See if you can substitute your coil spring system with ours. Our coil springs do not go up to 10 pounds, so you will need to use two of the S152-5 with the 15-177. For the double support, see our 15-150D.
