Product Description
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 21" 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.
