Universal Break-Off Link Arm, Fasteners; 1/2 inch increments, 1 per pkg.

This is a universal break-off link arm that makes it possible to adapt to whatever length link arm is needed when installing a louver or jalousie operator. Made of cadmium plated steel, it has break-off points between holes every 1/2 inches. This allows for a range from 1-13/16 inches to 5-5/16 inches in length. Any one of the lengths in between this range will be adequate for most situations.
