IO‑RL is the first full-size quick-change coupler designed specifically for photo, video, film and lighting
support. IO‑RL enables instant hardware swaps, replacing tedious threaded screw and hole connections.
IO‑RL provides a faster, more secure, hassle-free method of connecting lights, flashes and modifiers to
C-Stands and booms with no spin out.
IO-RL Lighting Stud Quick-Change Couplers are designed to connect professional lights to lighting stands
and mounting hardware. IO‑RL retrofits to conventional C-stands and lighting mounts and provides
instant IO quick-change compatibility.
