The Kirk PZ-141 is a quick-release camera plate that's designed specifically for the Nikon D7000. Its dovetail fits Arca-Swiss-style clamps to enable a quick release from a tripod head.
The plate is machined from 6061-T6 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-141 plate features a sensor-centering line on the side. Two Allen keys are included with the camera plate.
