The Kirk PZ-139 Camera Plate for Canon 60D is a quick-release plate that's designed specifically for the Canon EOS 60D. Its dovetail fits Arca-Swiss-style clamps to enable a quick release from a tripod head.
The plate is machined in the U.S. from 6061T6 aluminum, and it includes a stainless steel Allen screw for attaching it to the camera. Two additional screws serve as safety stops; in case the clamp is inadvertently left loose, the smaller screws will help stop the camera & plate from sliding all the way off the head.
The PZ-139 plate preserves access to the 60D's battery compartment, and it features a sensor-centering line on the side. Two Allen keys are included with the camera plate.
