Entrygard Dual Arm Operator, LH, Stud Bracket, 1 set per pkg.

This is a left handed Dual Arm operator with a 4-1/16 inch offset (up) link arm. The long continuous arm and the jointed arm create an action that pushes the sash open while pulling the hinge side of sash to the open position. This is the mechanism only - no cover or crank handle included (optional). The heavy duty diecast zinc operator base, worm drive, gears as well as the steel arms and stud bracket are protected with the corrosive resistant E-Gard coating process.
