Prime-Line Bronze Steel Right Single-Arm Casement Operator For Steel Framed Windows

This casement window operator is a right-hand Bronze Teardrop body type . It has a 9 in. steel arm with a round disc on the tip (some older styles had a small wheel instead of a disc). The disc slides in the H 3529 casement track located on the bottom of the casement window. It is worm gear driven by a 5/16 in. crank spindle. The matching crank handle that fits onto the crank spindle and installation screws are included. Mounting holes available are 3-7/8 and 4-3/4 in. on center.
