The 1.8" Quick Release Clamp with Classic Locking Knob from Kirk is designed to hold Arca-type compatible plates and mounts. The clamp is made of 6061-T6 aluminum, and it is anodized in a black and satin silver finish.
This 1.8" quick release receiver features a classic locking knob with a large, knurled design. Kirk's patented quick turn technology enables the clamp to open or close faster. With a counterclockwise 1/8-turn you can reposition the plate, or completely remove it with a half-turn. On the top of the clamp the laser-engraved sensor center lines help better position the camera when taking a photograph. The clamp has a recessed hole on its side to store the included 5/32" hex wrench.
NOTE: This clamp does not include a quick-release plate.
