This Heavy Duty 5/8 Swivel Pin adds articulation to your light stand giving you the option to turn you lights horizontally, vertically or facing up and down. One end slips onto a male 5/8″ pin while the other supports our light panels with a 5/8″ receiver. The ball joint allows 180° swivel of the fixture, while the large, rubber-covered T-handle provides secure locking in your chosen position. The barrel at the receiver end measures 1 1/8″. Removing the tightening knob from it allows you to drop it into a 1 1/8″ receiver.
