White vinyl tilt window. Need replacement parts.

Hmm..It looks like you have an old coil spring balance system. Our 15-140 pivot shoe may be used in this case. These are paired with the Series 150 coil springs along with the 15-143, 15-144, and 15-145 coil spring housing. You will need to provide us with the stamped number on the coil spring in order to choose the correct coil. We placed some media guides on this page in case you need some additional assistance.
