The Tool-Free Video Rigging Standard
Traditional camera accessories require Allen keys and multiple 1/4"-20 screws that loosen under dynamic camera motion. The NATO rail allows a camera operator to loosen a single ratchet lever by hand, slide off a top monitor or handle in two seconds, and stow the camera into a compact backpack without any tools.
