The DAC-60 60mm QR Clamp from Desmond is an Arca-type compatible quick release clamp. Made from aluminum, the clamp is 60mm long, and has a removable bull's eye bubble level. A numbered scale on both sides of the clamp allow for precise adjustments of your camera plate. The clamp has a 3/8"-16 thread, and includes a 1/4"-20 bushing adapter, so it can be mounted to most tripods or tripod heads.
