Improve device placement without redesigning the entire mount. The Gamber-Johnson MAX3 Extension 100 mm Assembly adds a controlled 100 mm offset to compatible MAX3 mounting setups, giving installers the extra reach needed to clear consoles, align peripherals, or improve operator access. It is designed for enterprise vehicle and mobile workstation environments where fitment precision matters as much as durability. For fleet, public safety, utility, and field service deployments, small adjustments can determine whether a system feels integrated or improvised. This extension helps close that gap by supporting cleaner geometry and more deliberate positioning within the existing MAX3 ecosystem. It is a practical choice when you need to preserve the base mount architecture while adapting to real-world cabin constraints. Use it to refine ergonomics, maintain equipment access, and reduce the compromises that come with generic spacers or improvised hardware. When the installation has to look intentional and perform consistently, a purpose-built extension assembly is the right part to specify.
