Series 810 Channel Balances

This is the SWISCO Series 810 Side-load Channel Balance Sash Support System (also known as a block and tackle balance) for non-tilt windows. The series is determined by the combination of the top and bottom fittings attached to the metal channel. When determining length, only measure the metal channel; do not include the fittings in this measurement.

The width of the metal channel measures 3/8". It houses a spring and pulley system to raise and lower the sash and comes fully assembled with a 19-023 top guide and a 15-077 bottom fitting, known as a shoe.
