SmallRig 5331 Double Head Crab-Shaped Clamp camera accessory

SKU CH-YFYG-F12FM

A double-headed crab-shaped clamp with two 360-degree ball heads and a magic arm mounts accessories up to 1.5 kg on tubes or surfaces 15 to 40 mm wide

  • Securely mounts accessories with 15-40mm jaw range and rubber pads
  • Lightweight 11.5 oz aluminum build adds minimal rig weight
  • Dual 360-degree ball heads enable precise angle positioning
  • Anti-deflection joint prevents loosening during movement
  • Supports up to 1.5 kg payload for reliable mounting

Versatile Mounting Clamp

The SmallRig 5331 double head crab-shaped clamp combines a universal magic arm with two adjustable clamps for flexible camera accessory mounting. Photographers and videographers can secure lights, microphones, or monitors to tubes, tables, or railings with a single tool.

1.5 kg Payload Capacity

The CNC-machined aerospace-grade aluminum and stainless steel construction supports a maximum payload of 1.5 kg (3.3 lb). This handles lightweight monitors, LED panels, or audio gear, but heavier cinema cameras or large telephoto lenses will exceed the rated limit.

15-40 mm Clamping Range

Each crab-shaped clamp opens from 15 to 40 mm (0.6 to 1.6 in) with non-slip rubber pads for grip on round or flat surfaces. The 360-degree ball heads with helical grooves allow precise positioning, though the fixed arm length and clamp span restrict reach to nearby mounting points.

Questions about this item

Will the 15-40mm jaw opening clamp onto my older light stand or tripod leg?

Yes, the clamp fits tubes from 15 to 40mm, so most standard light stands, tripod legs and railings are covered.

How can I verify the 360° ball heads and anti-deflection joint are holding firm after I mount a microphone?

Apply gentle pressure; the helical-groove ball heads should lock without drift and the magic-arm joint must not rotate under the 1.5 kg payload limit.

Does the box include both crab clamps and the magic arm, or do I need to buy the arm separately?

The package contains one magic arm and two crab-shaped clamps with rubber pads — everything shown is included.
