This Quick Release Dovetail has the quick release plat on the top and the dovetail on the bottom. It is design to let you mount 19mm or 15mm rail components which attach to the plate using two screws. Your Red camera attaches to the dovetail platform through a camera plate that attaches at the bottom of your Red camera. The Red quick release dovetail platform uses a dual-stage locking system which makes your camera package more secure as you mount it on your tripod.
