The Panavise Knuckle is a accessory bracket perfect for mounting an EFP-style LCD monitor. The bracket attaches to cameras with a 1/4-20 female screw (a shoe to screw adapter may be necessary and is sold separately), and mounts the monitor with a male 1/4-20 screw. The bracket is very positionable with a ball/socket that tilts 210°, rotates a full 360° and the monitor itself can turn a full 360. A large, easy to wing-type knob makes for quick for positioning and locks securely.
