Description
The RAM-TB-FHA2-1BU is a modular friction hinge arm designed for the RAM Tough-Bar system. It features a C size 1.5" RAM Pin-Lock ball, allowing you to connect a compatible C size double socket arm and device holder to build a customized mounting solution.
The integrated friction hinge provides smooth single-axis side-to-side adjustment, while the RAM Collar-Lock system helps prevent excessive rotation that could allow the attached arm or device to contact the dashboard.
