SmallRig Crab-Shaped Clamp with Ballhead Magic Arm 3757 is made of aircraft-grade aluminum alloy and stainless steel, CNC machined and carved to increase sturdiness and durability. It features a skeletal design and shark clamp with stronger clamping force as well as widely compatible 1/4"-20 threaded holes, 3/8"-16 threaded holes, and ARRI 3/8"-16 locating holes. The clamp, which supports a rod with a minimum diameter of 14mm and a surface with a maximum thickness of 65mm, can quickly attach cameras, monitors, LED lights, etc. to around pipes, cables, handlebars, tripods, and stabilizer handheld rings. In addition, built-in cushions provide protection and clamping stability. The ballhead magic arm consists of two ball heads and a ballhead clamp. An anti-twist design secures it to the crab-shaped clamp to prevent disconnection. The bottom ballhead is designed with a hex hole for enhanced fastening with the Allen wrench. The 360-degree adjustable ball heads feature anti-slip threads for easier locking and one 1/4"-20 screw to allow quickly connecting action cameras, monitors, LED lights, microphones, and other accessories.

 2. Please do not disassemble the original machine screw to replace the original ballhead magic arm, otherwise it may lead to thread failure.
