Kirk 2.4" Round Quick-Release Clamp with Extended Locking Knob

This 2.4" Round Quick Release Clamp with Extended Locking Knob from Kirk is a durable, aluminum quick-release clamp that is compatible with plates and brackets that have an Arca-type dovetail base. It features Kirk's patented quick-turn technology that provides the speed of a lever quick release with the added security and adjustability of a knob design. Simply loosen the knob approximately 1/8 turn counterclockwise to adjust or reposition the quick release plate. To easily top load or remove the quick-release plate, turn the knob 1/2 turn counterclockwise. This 2.4" diameter quick-release receiver features an extended locking knob with a large knurled design. The longer knob length makes it easier to use with larger cameras or camera rigs.
