The QRC-4.2 Quick Release Clamp from Kirk Enterprises is a 4.2" long clamp that is compatible with most Arca-type quick release plates. The clamp is made of a combined aluminum alloy and stainless steel construction to provide long-lasting dependability. Kirk's new clamp design also insures that no internal mechanisms are exposed, improving the clamps resiliency.
The clamp has also been engineered with safety stop relief grooves that provide improved safety when paired with Kirk camera plates. The clamp features a single spirit level to assist in proper leveling and centering lines for accurately positioning your camera within the clamp. A captive release knob has also been added to prevent the accidental loss of small internal parts and an internal slot has been added to hold the included 5/32 hex wrench.
