The H 3531 casement crank handle is aluminum die-cast and has a 5/16 in bore spindle. This fits any operator with a 5/16 in bore spindle such as the teardrop style casement operators (see H 3502 and H 3508). It offers excellent torque for easy opening and closing of windows. The crank handle projects out from the operator 2-11/16 in.
