Product Details:

Mechanism ONLY - Does Not Include Cover or Handle
From Truth Manufacturing
Dual Arm Action
Please, determine handing according to the picture

Dual arm action of the operator pushes the sash open while pulling the hinge side of the sash to the open position.
When properly installed, the result is an almost effortless operation of both casement and awning-type windows of varying sizes and weights, including those with insulated and double-insulated glass.
Typical operating torque is less than one foot-pound to open and close a 60 pound (27.2 kilogram) sash to 90º.

Plastic or Metal Covers and Handles for this operator mechanism are available. Please, choose a handle with 11/32" Spline (Crank or T-Type).
