Beginning with your pivot shoe, our 15-191 may work great as an alternative. Just confirm the measurements are a match with one another. This can be used with the Series 160 coil spring. Your spring should have a number stamped on it. Please provide that number to us. If there is not a number, please get back to us with the weight of your window sash. Lastly, for the coil support, is our 15-150S compatible with your support? Get back to us and let us know. |
