iFootage Spider Crab MA3-4 7" Magic Arm with QR Cold Shoe and Combo 1/4"-20 / 3/8"-16 Module

A compact, flexible 7" magic arm, the iFootage Spider Crab MA3-4 uses quick-release (QR) mounting modules on both ends to speed setup and protect attached accessories. The arm supports up to 13.2 lb (6kg) and is made from aluminium alloy and stainless steel, weighing 380g.

One end features a QR cold shoe foot while the other has a combination QR mounting module that accommodates 1/4"-20, 3/8"-16, and 3/8"-16 with ARRI-Anti-twist pins. The combo module includes a flip-up twist tab: twist to use the 1/4"-20 thread, continue to raise the 3/8"-16 sleeve, and keep turning to engage the ARRI anti-twist pins; reversing the tab disengages the pins and then the sleeve.

QR attachment modules let you mount the small receiver to an accessory, camera, cage, or support, then click the arm onto the module and secure it using the dual locking system. This workflow avoids maneuvering the full arm when attaching gear, allows leaving QR plates on items for transport, and supports pre-attaching extra modules to accessories for even faster rigging.
