Movable hooks slide on and off the flyer arms. Orient the new hook so that it curves inward and position it where you like on the flyer arm.
To install or remove a screw eye, slide the shaft of a screwdriver through the eye. Use the screwdriver as a lever to turn the screw eye, loosening or tightening it. When you install a new screw eye, make sure it's angled as shown as in the photo above—it should not strike the mother-of-all as the flyer rotates.
