Tether Tools TetherBlock Arca - Graphite

The thunder gray TetherBlock QR Plus Quick Release Plate from Tether Tools is designed to adapt a camera to an Arca-type compatible quick release clamp and prevent damage to the camera's data port while tethered to a computer or hard drive.

Along the 1/4"-20 mount and anti-slip pads on the QR Plus's top surface are grooves that can channel a section of data cable into one end of the plate's length and out the other before the plate is attached to a compatible camera. This allows a USB or FireWire cable that is connected to a camera's data port for tethered photography to be secured under the camera and within the QR Plus. Before being able to reach the point at which a data cable and a camera connect, tension along the cable which could then occur from accidentally tugging or tripping on it is interrupted by the plate's grooves. Strain from abrupt and incorrectly angled detachment of a data cable that could otherwise dislodge a camera's data port or cause it to function improperly is avoided.

For direct attachment to accessories such as a tripod or straps that feature 1/4"-20 mounts, the underside of the plate is tapped with two 1/4"-20 female accessory threads.
