Steel Casement Operator, 8 in. Arm, Teardrop Housing, Aluminum, Right Single Pack

This casement operator is constructed of a diecast body, a hardened steel arm (with a steel guide button at 9/16 in. in diameter), and a case-hardened worm gear mechanism that comes in a corrosion resistant plating. It features a teardrop-shaped housing and an operator crank handle, and comes finished in an aluminum painted color. This Prime-Line casement operator is right-handed, determined when viewing the window from the inside looking out. It is a face-mounted design that installs on older, crank-out casement, steel window frames with 3-7/8 in. and 4-3/4 in. mounting hole centers. This high-end quality operator exhibits minimal gear lash, with positive and smooth operation. For the opposite handing of this operator, see Prime-Line part H-4281. Installation fasteners and a set screw (for affixing the crank handle onto the operator spindle) are included with each operator.
