The Avenger D700B is a convenient lighting tool for studio or location, letting you clamp a reflector to a light stand (both sold separately) and easily adjust its angle and direction. If you can't convince a friend to come to your shoot and hold your reflector for you, this disc holder will come in very handy. In excellent condition, with only light wear. Also worth noting if you're not familiar with the Avenger brand name that this is not a weird knockoff: it's Manfrotto's lighting and grip sub-brand.
