IO-RL is the first full-size quick-change coupler designed specifically 
for film/photo/video lighting support. IO-RL enables instant hardware swaps, replacing the tedious threaded screw and hole connections between lights, modifiers and stands. IO-RL provides a faster, more secure, hassle-free method of connecting speed flashes, lights and modifiers to stands and booms with zero spin out.
