The 1.65" Desmond DAC-42 QR Clamp supports Arca-standard quick release plates. It can be attached to most ball heads, mini tripods, and other camera supports using an included 6mm screw. On the bottom, the clamp features a 3/8"-16 thread and comes with a metal 1/4"-20 adapter. The clamp measures 1.65" in length, and the QR plate platform is adjustable from 37.25 to 41.5mm. The bubble level is removable to let you have a slimmer profile.
