Product Information

Overview

The RAM® Friction Hinge 6" Arm & 6" Swing Arm with Ball for Tough-Bar™ (RAM-TB-FHA3-SW1BU) is a versatile attachment designed to mount a keyboard or other accessories to the RAM® Tough-Bar™ with smooth, controlled adjustability. This system combines a 6" friction hinge arm, a 6" swing arm, and a C size RAM® ball for full multi-axis positioning. The friction hinge delivers precise single-axis pivoting, ideal for moving a keyboard side to side, while the swing arm adds 360° of horizontal rotation. The integrated ball and socket connection allows for fine tilt adjustments, letting you position your accessory exactly where you need it or quickly move it aside to access vehicle controls. The built-in cable retention feature keeps cords neatly organized and secured along the arm, preventing snags or strain during adjustment. For added protection, the Collar-Lock™ system acts as a rotational limiter, blocking over-rotation that could send the mount into the dashboard during movement or impact. Together, these components ensure stable, vibration-resistant performance in demanding environments. Complete with a round ball base for compatibility across the RAM® Mounts ecosystem, the Friction Hinge 6" Arm & Swing Arm for Tough-Bar™ offers rugged flexibility and clean cable management for fleet, commercial, and personal vehicle setups.
