FANAUE DA-150PRO double socket swivel arm (5.9-inch) for RAM-style mounts

Quick take

The FANAUE DA-150PRO is a 5.9-inch double-socket swivel arm for RAM Mounts B-size (1-inch ball) systems. Buyers tend to describe it as sturdy and well-made, with ball joints that lock down tightly for stable positioning on bumpy rides. The key buying caveat is compatibility: it only works if your existing clamp, base, and ball components use the same 1-inch B-size standard.

Pros and cons

Pros

  • Tight ball locking that helps prevent slipping during movement
  • Double ball joints for more articulation and angle fine-tuning
  • Compact 5.9-inch length that balances reach and bulk
  • Aluminum construction positioned for durability in vehicle use

Cons

  • Compatibility depends on RAM-style B-size (1-inch ball) components
  • Not intended as a complete mount kit, you still need the right base and device-specific holder

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence highlights three recurring themes. First, people frequently mention that the double-socket arm feels well-built for the price, especially for motorcycle and action-cam setups. Second, the ball system is repeatedly described as locking down firmly, helping maintain the chosen angles even when riding over bumps. Third, buyers appreciate the rotation and adjustability, using the arm to dial in device placement without ending up with a bulky setup.

Because the review snippets provided are uniformly positive and there is limited detail on failures or long-term wear, buyer-review evidence is not enough to draw a broader pattern about issues like corrosion, long-term joint behavior, or service experiences.

What the FANAUE DA-150PRO is for

This is an interconnecting arm for vehicle mounting systems built around RAM Mounts B-size (1-inch ball) components. In practical terms, it lets you extend and reposition your setup by adding a short, adjustable link between the base (clamp or mount) and your device holder.

It is commonly used for things like GPS units, smartphones, and cameras, including action cameras, when the goal is stable framing and repeatable angle adjustment.

Key features that matter when you are mounting gear

Double socket articulation for flexible angles

Two ball joints provide multiple points of movement, so you can aim the device more precisely than a fixed arm. This is especially helpful when you need to clear handlebars, match sightlines, or avoid screen glare.

1-inch B-size ball compatibility (RAM-style)

The arm is designed to work with RAM Mount B-size components and compatible 1-inch ball assemblies. If your current system uses a different ball size or a non-ball mounting interface, this arm will not be the right upgrade path.

5.9-inch medium reach

The 5.9-inch length is a middle ground between short positioning arms and longer extenders. It is long enough to get the device into a comfortable viewing or recording angle while still staying relatively compact for handlebar or other tight mounting locations.

Aluminum build for regular outdoor use

The arm uses aluminum for the main body, which is typically chosen for a balance of strength and weight in mount accessories. The product is positioned for multipurpose vehicle use scenarios, including automobiles and bikes.

When you should look elsewhere
