Kupo KG037211 Super Knuckle with Baby Receiver

The Kupo KG037211 Super Knuckle with Baby Receiver is a modular mounting adapter built around a double-ended shell housing two independent ball joints. This design gives you full 3D articulation on both sides of the knuckle, allowing precise angular positioning of whatever accessory is attached. The central locking knob simultaneously tightens both ball joints, so a single twist locks your entire setup into place — a significant time saver when making rapid adjustments during a shoot or on a live production set.

One end features a standard 5/8" baby receiver for grip arms, spigots, and light fixtures, while the other provides a 1/4"-20 male thread with a locking thumb wheel for cameras, monitors, and smaller accessories. The aluminum alloy construction keeps the total weight at just 10.4 ounces while supporting loads up to 17.6 lbs. As part of Kupo's broader Super Knuckle ecosystem, the end accessories are interchangeable, meaning you can reconfigure the knuckle for different tasks without buying entirely new hardware. For grip technicians and photographers who need a reliable, compact articulating mount, this is a versatile addition to the kit.
