SmallRig 1855 Overview
The SmallRig S-Lock Quick Release Mounting Device is designed for most 1/4"-20 gear. It is made up of two parts, namely a male plate and a female plate. Attach the male plate to the bottom of a monitor via an included 1/4"-20 tie-down screw. The male plate and the female plate are locked tight via a spring spanner, thus the plates could be attached and detached quickly and conveniently and switched to other application scenarios if necessary.
 
It comes with M2.5 threaded holes to mount an optional cold shoe. It is equipped with 1/4"-20 and 3/8"-16 threaded holes that are compatible with magic arms with 1/4"-20 or 3/8"-16 screws. The counterbored hole is utilized to mount the monitor, plates, and handles with 1/4"-20 or 3/8"-16 screws.
