The Kirk PZ-143 Camera Plate for Nikon D7000 With MB-D11 Battery Grip is a quick-release plate that's designed specifically for the Nikon D7000 with a MB-D11 battery grip attached. 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 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.
Two Allen keys are included with the camera plate.
