This is an original design of SmallRig Quick Dovetail 1537
SmallRig Quick Dovetail 1537 is a short dovetail in Manfrotto standard. Two unthreaded holes for you to mount it on a cheese plate or a rod clamp: one for 1/4'' screw, one for 3/8'' screw. A small aluminum bar mounted on it with two M4 screws works as anti-twist. This dovetail can slide into baseplate from either forward or backward.
