Overview

The Neewer ST83 Super Clamp with Dual Ballhead Magic Arm is a mounting kit built for photographers, videographers, and content creators who need to attach gear to surfaces and poles without dedicated mounting hardware. The super clamp opens wide enough to grip objects between 0.6 and 2.4 inches in diameter, making it compatible with tripod legs, light stands, desk edges, motorcycle handlebars, selfie sticks, and even 25mm and 30mm gimbal stabilizer rods from DJI Ronin-M, Ronin MX, and Freefly MoVI systems. Nonslip rubber pads line the jaws and mounting plate to protect equipment while maintaining a secure hold.

The 3-inch magic arm features two independently adjustable 360-degree ballheads, locked down via a single screw knob for quick positioning. Mounting versatility is a strong point of this kit: 1/4-inch threaded holes provide standard camera and accessory connections, ARRI locating points add compatibility with cinema-style gear, and the built-in cold shoe mount accepts LED lights and microphones directly. The kit ships with a phone holder for devices 2.2 to 3.3 inches wide and adapters for popular action cameras. Constructed from CNC-machined aluminum alloy and stainless steel, the ST83 supports loads up to 6.6 pounds, making it well-suited for smartphones, action cameras, small monitors, and compact camera setups.
