The Omega coil springs, like the ones show in your photos, have been shortened from 62" to 35". In this case, you will need to move the installation of the coil spring housing just below the center of the window track. That way, when you close the bottom sash, the top tilt latches don't hit them. Right now you're showing a pivot shoe that looks very similar to the 15-111, however, you may want to to with the 15-191 that is made of a stronger resin in the nylon. For the coil itself, the S152-5 should work for you. |
