Adjustable Multi Angle 9.5in Aluminum Arm Support - Solid Mounting

In this review the Adjustable Multi Angle 9.5in Aluminum Arm Support is evaluated for drivers, vloggers, and action camera users who need a sturdy, adjustable extension between a suction pad mount and a 20mm ball head. The bottom line: this arm delivers a durable, vibration-resistant aluminum solution for deeper dashboards and windshields, with dual ball and socket joints and a locking elbow that make positioning straightforward. It is best chosen when long-lasting metal construction and compatibility with 20mm systems are the priority.

Key Features

• All-aluminum construction: The full aluminum build provides a rigid, corrosion-resistant arm that stands up to regular vehicle use and rougher conditions.
• 9.5in adjustable length: The three-arm design reaches 9.5in for extended placement and can be shortened to about 6in by removing the long arm for tighter installations.
• Dual ball and socket joints: Multiple articulation points allow for precise positioning and a broad range of viewing angles to suit smartphones, cameras, and action cams.
• Locking elbow joint: The elbow lock secures intermediate angles so the arm holds steady even on bumpy roads or during motion.
• 20mm ball system compatibility: Machined to work with common 20mm ball mounts from major manufacturers, enabling integration with many existing mounting setups.

Who It's For

This arm is aimed at car and truck drivers, vloggers, and action cam users who need a robust, metal mounting link for deeper dashboards and windshields. It suits people who already use 20mm ball systems and want a vibration-free, adjustable solution that can be shortened for tighter installs.

Those who should look elsewhere include users who require a complete mounting kit with ball ends included or people using 17mm ball systems, since the arm is not compatible with 17mm balls and the 20mm ball ends are sold separately.

Pros & Cons

Pros

• Sturdy aluminum build that reviewers describe as quality and durable for repeated use.
• Flexible positioning with dual ball joints and a 180 degree center turn for fine adjustments.
• Length options (9.5in full or shortened to about 6in) make it versatile for different vehicle setups.
• Works with 20-21mm ball systems so it integrates with common aftermarket ball mounts.

Cons

• 20mm ball ends are not included, so buyers must purchase compatible ball mounts separately.
• Not compatible with 17mm ball mounts, limiting fit with some older systems.
