The pivot shoe that will fit into this window is our 15-199. Carefully compare your measurements with ours to confirm this is correct. These shoes are used with a Series 160 coil spring. You will need to retrieve the stamped number from the coil in order to choose the proper springs. If there is not a stamped number, get back to us with the weight of your sash.
