The Kupo KS-273 V-Lock Set provides a compact, quick-release V-lock solution for filmmakers. It includes a wedge and base that are precisely machined from black anodized aluminum.

Key features and benefits

• Precision-machined wedge and base made from black anodized 6061 aluminum for consistent fit.

Mounting, compatibility and usage

The V-Lock wedge bolts using M3 screws to the standard V-mount battery. In addition, the wedge can attach to any device that has either a 1/4”-20 or 3/8”-16 hole by using the supplied screws. This gives you straightforward compatibility with common camera accessories and plates.

Meanwhile, the V-lock base can bolt using M5 fasteners to attach to a Convi clamp by using the supplied screws together with the included 3/8” to M5 adapter. The base also features two 3/8”-16 tapped holes on the back, spaced 1” center-to-center, which lets you mount the base onto any standard cheese plate.

The extension handle is equipped with a 1/4”-20 male thread. When mounted on the knob, the handle allows an extension of up to 25 cm, giving you extra reach or leverage when needed.
