Prime-Line H 4288 9 In. Aluminum Teardrop Type Right-Hand Casement Operator (Single Pack)

This casement operator is constructed of a diecast body, a hardened steel arm (with a steel guide button at 9/16 inch 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 inch and 4-3/4 inch 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 model number H 4282. Installation fasteners and a set screw (for affixing the crank handle onto the operator spindle) are included with each operator.
