This is a Series 230 replacement constant force balance system for tilt windows. It moderates the operation of your window sash using a specifically calibrated coil spring that allows the window to stay open when raised and remain shut when closed.

• This balance comes complete with a pivot cam, coil spring, coil spring cover, and mounting bracket.
• The spring is stainless steel and coated for low friction and corrosion resistance.
• Fits pocket size 1.292" x .562".
• A pair of 10 lbs assemblies will carry 16.01 to 18 lbs, (sold individually). The weight you need should be indicated as a stamp or imprint on your old balance cartridge cover.
