This is a Series 765 channel balance for tilt-in 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 36” long metal channel.
Comes fully assembled with a screw clip on top and a pivot shoe hook attached at the bottom 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.
Can work for either the left or right side of the window interchangeably.
Used in American Craftsman and Silver Line vinyl, single hung, new construction windows, as well as Silver Line Series 1200 vinyl, double-hung, replacement windows.
