The Jmary MB-42A Articulated Magic Grip Arm is an 11-inch friction arm that locks every joint at once with a single central knob. Position the arm where you want it, tighten one handle, and the whole assembly goes rigid — which is why arms of this design have been a studio and on-set standard for decades.
Rated to a 15kg payload while weighing 1.10kg itself, it is substantial enough to hold a monitor, a light, a microphone or a secondary camera rather than only small accessories. The MB-42A terminates in a male 1/4-inch screw, so it threads directly into the 1/4-inch socket found on monitors, cages, small lights and ball heads.
Key Features
- Single-knob locking: One central handle locks all joints simultaneously, so repositioning is a two-second operation rather than a sequence of separate adjustments.
- 15kg payload capacity: Enough for field monitors, LED panels, microphones and secondary cameras, not just lightweight accessories.
- 11-inch reach: Long enough to place a monitor or light exactly where it is needed while keeping the clamp out of frame.
- Male 1/4-inch screw: Threads directly into the standard 1/4-inch socket on monitors, camera cages, small lights and ball heads with no adapter.
- Full articulation: Multiple pivot points allow almost any angle, including awkward low and overhead positions that a fixed bracket cannot reach.
- 1.10kg build: Metal construction heavy enough to stay rigid under load without adding meaningful weight to a rig or light stand.

Frequently Asked Questions
How much weight can the MB-42A hold?
It is rated to a 15kg payload, which comfortably covers field monitors, LED panels, microphones and most secondary-camera setups. The arm itself weighs 1.10kg.
What is the difference between the MB-42A and the MB-42?
The thread. The MB-42A has a male 1/4-inch screw, which threads directly into a monitor, cage or light. The MB-42 has a female 1/4-inch socket, which instead accepts a screw from the accessory. Choose based on which end your equipment provides.
How does a magic arm lock?
A single central knob tightens all the joints at once through the friction mechanism inside the arm. You position the arm freely with the knob loose, then tighten once and the entire assembly holds its shape under load.
What can I attach it to?
Magic arms are normally paired with a super clamp, which grips a light stand, scaffolding pole, table edge or car window. The arm provides the articulation and the clamp provides the anchor point.
