This casement window operator is a left-handed bronze square 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 Prime-Line part H 3529 casement track located on the bottom of the casement window. It is worm gear driven by a 3/8 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 in. and 4-3/4 in. apart.
