Series 500 Spiral Balance

The SWISCO Series 500 Spiral Balance is a popular balance that is used in both wood and aluminum non-tilt windows. When determining length, only measure the metal tube.

The tube measures 9/16" in diameter but it is considered 5/8" in the trade and houses an internal spiral rod with cross-piece. Spiral window balances come fully lubricated and ready to be charged.
