SmallRig Super Clamp with Double Crab-Shaped Clamps 4103 is made of aircraft-grade aluminum alloy and stainless steel, CNC process anodized and carved to increase sturdiness and durability. It features a skeletal design and shark clamp with stronger clamping force as well as widely compatible 3/8"-16 threaded holes and ARRI 3/8"-16 locating 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 umbrellas, selfie sticks, microphones, etc. to round pipes, tables, handlebars, tripod rods, and handrails. Built-in cushions provide protection and clamping stability. The ball head magic arm consists of two ball heads and a ball head clamp. Anti-slip threads help 360-degree adjustable ball heads lock easily and a one-piece connection secures the ball head to the clamp to prevent disconnection. This item works well with Flexible Vlog Tripod Kit VK-19 (Black) 3904.
