The QRC-3.18EK Arca-Type 3.18" Quick Release Clamp with Extended Locking Knob from Kirk is a 3.18" 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. This 3.18" 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. The clamp design also insures that no internal mechanisms are exposed, improving the clamp's 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.
NOTE: This clamp does not include a quick release plate.
