RAM MOUNTS Swivel Double Socket Arm, B Size 1" Ball (RAP-B-200-2U)
Quick take
This RAM double socket swivel arm upgrades a RAM ball-and-socket setup by adding more positioning freedom, with 360° center rotation and a 180° swivel joint. It is a good fit for mounting phones, GPS units, or cameras on a vehicle or dash when you want fine-tuning instead of a single pivot. The biggest practical caveat is that longer, heavier configurations can increase vibration, and this arm is composite rather than metal.
Pros and cons
Pros
- 360° center rotation plus a 180° swivel joint for flexible device positioning
- Designed for RAM B-size 1" ball components, so it integrates with a wider system
- Near-infinite adjustability using double ball and socket technology
- Holds up to 2 lb for standard use (1 lb heavy-duty use)
Cons
- Composite construction, some buyers would prefer metal for reassurance
- Not always as rigid as expected when installed on a dash, movement can transfer to the device
- Extra arm length can increase vibration on phones depending on your setup
What buyers think
Buyer feedback centers on adjustability and holding power. Many reports highlight that separate controls for the swivel points make it easier to dial in the exact angle compared with simpler single-arm designs. Build quality is broadly viewed as strong for the job, even though the arm is not metal, with a recurring theme that the composite feels sturdier than expected. The most consistent limitation mentioned is stability under real-world driving, where a longer heavier configuration can allow noticeable bounce or vibration at the mounted device.
What this arm is for
The RAP-B-200-2U is not a complete phone or GPS mount by itself. It is an articulating “bridge” piece that connects to other RAM B-size 1" ball components (for example, a mounting base and a device holder). If you already have a RAM mount system and you feel your current arm or angle options are limiting, this double socket arm adds additional rotation points so you can place the device more precisely.
Key specs that affect real use
- Adjustability: 360° rotation at the center pivot, plus a 180° swivel joint for changing the overall viewing angle.
- Compatibility: B size (1") ball system components. The arm attaches to any B-size RAM ball components, including bases and device holders.
- Size: Overall length is 6.25" (socket-to-socket length 5.5").
- Weight capacity: Standard use rating is 2 lb, heavy-duty use rating is 1 lb.
- Material: High-strength composite (composite “instead of metal” is a common discussion point in reviews).
- Weather resistance: Not rated as water resistant.
Pros and cons for different setups
Best for
- Dash and vehicle mounting with a RAM system: You want more angles than a short, single-control arm provides.
- Phones, GPS, and cameras: When you need flexible positioning for visibility and safer viewing.
- Buyers who value precise adjustments: Dual swivel control points make it easier to fine-tune placement.
Who should be careful
- Anyone mounting a heavier device or using a long configuration: Extra length can transmit vibration, which some reviews describe as noticeable on phones.
- Buyers expecting a rigid, “no movement” feel: The arm can function well and still allow some bounce depending on how the rest of your mount is secured.
- Outdoor, wet conditions: This arm is not listed as water resistant, so protection may be needed in rain or exposed environments.
Is it worth it?
If you already own compatible RAM B-size (1") ball components and you want more positioning capability, the RAP-B-200-2U is the kind of accessory that can meaningfully improve how your device sits. It is especially appealing when you are replacing a simpler arm that feels limiting because you have more rotation points to dial in the angle. The decision comes down to your tolerance for setup tradeoffs: because it is a longer composite arm in a multi-joint configuration, some buyers report increased vibration or less rigidity than they would like, especially when the mounted device is on the end of the longer setup.

Alternatives to consider
Without naming specific brands, here are the main “apples to apples” comparison categories shoppers typically weigh with RAM-style mounts:
- Shorter or single-joint arms: Better if your priority is rigidity and minimizing vibration, though you may lose some fine-tuning options.
- Different ball sizes (C or D): Choose this only if you are committed to B-size (1") components. If your system uses other sizes, compatibility is the first decision point.
- More compact mounting solutions: If your device needs a stable, low-movement setup, you may prefer fewer joints or a configuration with less cantilever length.
FAQ
How do I know this is compatible with my current RAM mount?
This arm is made for RAM B-size (1") ball components. As long as your base and your device holder both use B-size 1" RAM balls, it should integrate with your existing system.
What is the adjustability range on the RAP-B-200-2U?
It provides 360° rotation at the center pivot and a 180° swivel joint, letting you change both rotation and the overall viewing angle.
How much weight can it hold?
It is rated for standard use up to 2 lb and heavy-duty use up to 1 lb. For best results, consider the weight of the device plus any added accessories and be conservative if you want maximum stability.
Is this arm metal or composite?
It is a high-strength composite arm. Some buyers would prefer metal, but feedback generally indicates the build feels solid for its purpose.
Will it work for outdoor or wet environments?
It is not listed as water resistant. If your mount will see rain or heavy exposure, plan on additional protection and consider your vehicle’s exposure level.
Does the longer arm increase vibration?
Extra length can increase motion transfer to the mounted device depending on your vehicle surface, mounting base, and how your system is tightened. Some reviews specifically mention that longer configurations can make phone vibration more noticeable.
