The RAM® Friction Hinge Arm with Pin-Lock™ Ball for Tough-Bar™ (RAM-TB-FHA2-1BU) is a modular attachment designed to let you build your own C size mounting solution on the RAM® Tough-Bar™. This setup features a C size RAM® Pin-Lock™ ball, allowing you to connect any C size double socket arm and device holder—ideal for tablets, GPS devices, or other accessories. When paired with a C size arm, this configuration offers up to 180° of articulation, while the integrated friction hinge provides smooth, single-axis pivoting for fine-tuned positioning or quick access to vehicle controls. For added safety, the Collar-Lock™ system acts as a rotational limiter, preventing over-rotation that could send the arm or device into the dashboard during adjustment or impact. Together, the friction hinge and Collar-Lock™ provide stable, vibration-resistant performance even in demanding environments. The built-in cable retention feature keeps cords neatly organized and secured along the arm, preventing snags or strain during adjustment. With its durable construction and RAM® compatibility, the Friction Hinge Arm for Tough-Bar™ delivers customizable adjustability, secure hold, and reliable protection for your equipment and vehicle interior.
