The Induro QRT50 Quick Release Clamp is an Arca-Swiss-style quick-release clamp that comes with a compatible 2x2" camera plate with a standard 1/4"-20 screw for mounting most cameras. The clamp mounts to an existing tripod head or monopod, especially one that does not feature a quick-release system, so you can easily attach a camera and remove it from your support. For mounting to a tripod head or monopod, the QRT50 clamp is compatible with standard 3/8"-16 screws and, via its included adapter, 1/4"-20 screws.
The QRT50 clamp comes with the PU-50 plate, but its Arca-style twist-lock is compatible with other plate sizes as well, allowing you to match your specific camera/lens setup to the optimal size and brand of dovetail plate. A double-action safety lock enables the plate to slide and adjust within the clamp for proper positioning, without the plate & camera sliding all the way out of the clamp.
