This looks like our 15-180 Coil Balance Shoe. This is compatible with Series 190 Coil Springs. You will need to look for stamped numbers on the coil springs to know which spring weight you need. If these are not available, let us know how many coil springs are on each side of the window sash, as well as the weight of the window sash, and we should be able to work out a solution for you. Many thanks.
