Series 600 Spiral Balance
The SWISCO Series 600 Spiral Balance is the most popular spiral tilt balance in the industry, used in aluminum and vinyl tilt-in windows. When determining length, only measure the metal tube.
The tube's diameter will actually measure 9/16", but it is considered 5/8" in the trade. This balance uses double pins at the end of the spiral to catch the pivot shoe. Spiral window balances come fully lubricated and ready to be charged.
