Overview

The Neewer ST88 Super Clamp with Dual Ballhead Magic Arm is a compact mounting solution built from black anodized aluminum alloy. It combines a gear-driven super clamp, a 3-inch articulating arm, and two independently rotatable 360-degree ball heads into a single integrated unit. The clamp grips round poles and tubes between 0.8 and 2 inches in diameter or flat surfaces up to 2 inches thick, with nonslip rubber pads to protect equipment and maintain a secure hold. Three pivot points on the clamp body add stability beyond what a basic clamp provides.

Mounting versatility is a key strength of this kit. The arm terminates in a 1/4-inch screw compatible with compact DSLRs, mirrorless cameras, LED panels, monitors, and microphones, while the clamp base offers 1/4-inch and 3/8-inch locating holes along with a built-in cold shoe. An adjustable phone holder and an action camera adapter come included, covering smartphones and GoPro-style cameras without extra purchases. At 6.6 pounds maximum load capacity, the ST88 is best suited for lightweight to mid-weight gear rather than full-size cinema rigs.
