Henderson 162521 3″ Double Socket Arm for 1″ Ball Mounts

Achieve Perfect Positioning and Unshakeable Stability

In the demanding environment of a work truck cab, keeping your essential electronics secure and perfectly positioned is not just a convenience—it’s a necessity for safety and efficiency. The Henderson 162521 3″ Double Socket Arm is the cornerstone of a reliable mounting system, designed to connect your device cradle to its mounting base with absolute security. This medium-length arm provides the ideal balance of reach and compactness, allowing you to position GPS units, spreader controllers, tablets, or smartphones exactly where you need them, without obstructing your view or controls. Its robust design ensures that even on the roughest roads or during intense snow-clearing operations, your equipment stays locked in place.

Infinite Adjustability and Rock-Solid Grip

The genius of the Henderson 162521 lies in its simple yet incredibly effective design. Featuring sockets at both ends that accommodate standard 1-inch (B Size) ball bases, this arm offers near-infinite adjustability. A single, easy-to-grip knob on the side of the arm controls the tension on both sockets simultaneously. Loosen the knob to smoothly pivot and rotate your device to the perfect viewing angle, then tighten it to create a rock-solid, vibration-resistant hold. This single-point adjustment system allows for quick, on-the-fly changes, ensuring you can adapt to changing conditions or switch operators without hassle. This arm is the key to creating a truly ergonomic and customized cab environment, reducing operator strain and improving focus.

Built for the Toughest Professional Environments

Durability is non-negotiable for professional-grade equipment, and the 162521 mounting arm is built to exceed expectations. Constructed from high-strength, powder-coated marine-grade aluminum, it is engineered to withstand the daily abuse of commercial use. This material provides an exceptional combination of light weight and immense strength, while the powder-coated finish offers superior resistance to corrosion, scratches, and chemicals commonly found in winter maintenance environments. As an official component from Henderson, you can trust it to integrate seamlessly with your existing setup. Whether you’re outfitting a new vehicle or upgrading an old one, this component is a vital piece of the puzzle, and you can find it alongside other essential Henderson Snow Plow Parts to complete your system.
