Series 351 Channel Balances

Series 351 Sideload Channel Balance Sash Support System (also known as a block and tackle balance) for non-tilt windows. The metal channel’s width is 9/16”, which is considered 1/2" in the trade. The metal channel houses a spring and pulley system to raise and lower the sash. The Series 351 comes fully assembled, with a non-winged 19-002 top guide and non-winged 15-002 bottom fitting called a shoe. The shoe measures 1” deep.

The series 351 closely resembles the Series 390 Channel Balance. The difference lies in the depth of the shoe. The Series 390 has a 15-001 shoe that measures 1-1/8” deep.
