The 4213 Reflector Holder Arm is designed to support pop-up reflectors and backgrounds featuring an internal metal spring frame. Its adjustable jaws securely grip the frame, providing a stable hold during use. With a three-section extendable design, the arm accommodates a variety of reflector sizes. Simply mount it to the top of a light stand, and use the ball-socket joint to easily tilt, rotate, and position the reflector for optimal lighting control.
