The SmallRig 6021 Quick Release V-Lock Mount Plate Kit is a lightweight, portable solution designed to enhance setup flexibility for videographers. The kit includes a V-Lock mount and a V-Lock plate.
The V-Lock mount can be attached to cages or handles featuring two 1/4"-20 threaded holes with an 18mm (0.7in) spacing. It pairs with the V-Lock plate, which is equipped with one 1/4"-20 threaded hole and one 1/4"-20 locating hole, allowing for the quick attachment and detachment of accessories like magic arms (ID3873,3874), wireless video transmitters, and more. Alternatively, it can be used directly with V-Mount batteries (ID3580B,3579B).
