This is a Series 385 channel balance for non-tilt windows. It moderates the operation of your window sash using a specifically calibrated spring and pulley system that allows the window to stay open when raised.
- This balance has a 33" long metal channel. When determining the length, do not include the attached fittings. Only measure the metal channel.
- Comes fully assembled with the 19-005 top and 15-004 (1-3/32" deep) bottom fittings and will be ready to install out of the box.
- The strength you need should be indicated as a stamp or imprint on your old metal channel. If you do not have a stamp, or cannot match it up to our options, weigh your sash on a scale and refer to the chart below.
- The width of the metal channel measures 9/16" but is considered 1/2" in the trade.
- Can work for either the left or right side of the window interchangeably.
