Series 500 Spiral Balance

This popular balance is used in both wood and aluminum non-tilt windows. The series 500 sash support system features a spiral tube balance with a cross piece. The metal tube has a diameter that will actually measure 9/16" but it is considered 5/8" in the trade. The balance tip is available with red or blue bearings for most lengths. Spiral window balances come fully lubricated and ready to be charged.
