We appreciate you contacting us with your hardware needs. Starting with your pivot shoe, see if our 15-192 is a good match. These are used with the Series 170 coil springs. See if you should have any stamped numbers on your spring. If so, get back to us with that information. If not, let us know the weight of your window sash and we will go from there. |
