The Genustech G-ARM Articulated Arm by Noga is designed to mount different accessories to a plate system for configuration. It enables you to quickly get your on-board light, monitor, etc. into position. The Noga arm offers the conventional 2-arm system in which a vertical column is connected to a horizontal arm by a swivel clamp, which allows flexible tightening in any position. Top, center, and bottom joints are all automatically locked in position by tightening a single screw. The arm comes with 2x 1/4" screws to attach to your cheese plate / cheese bridge / cheese rod.
