Product Description


SmallRig Crab-Shaped Clamp with Ballhead Magic Arm 3757B

SmallRig Crab-Shaped Clamp with Ballhead Magic Arm 3757B 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, and 3/8"-16 threaded holes. The clamp, which supports a rod of a minimum diameter of 14mm and a surface with a maximum thickness of 65mm, can quickly attach cameras, monitors, LED lights, etc. to round pipes, tables, handlebars, tripods, and stabilizers 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.
