RAM Mounts Double Socket Arm with Retention Knob – B Size Short

The RAM Mounts Double Socket Arm B Size Short is a high-strength composite connecting arm designed for RAM Mounts‘ 1″ ball mounting system, featuring dual sockets and a retention knob for secure device positioning on motorcycles and vehicles. This short-length arm provides compact connectivity between any RAM B-size ball components, making it ideal for handlebar-mounted phone holders, GPS units, and action cameras where space is limited. The retention knob prevents loosening from vibration, ensuring stable mounting even on rough Indian roads.

Technical Specifications

Key Features

Retention Knob System: The integrated retention knob locks the ball-and-socket connection tighter than standard RAM arms, preventing loosening from engine vibration or rough terrain – critical for Indian highway conditions and off-road riding.

High-Strength Composite Construction: RAM’s proprietary composite material offers superior strength-to-weight ratio compared to aluminum arms while remaining rust-proof and weather-resistant for monsoon durability.

Universal B-Size Compatibility: Works with any RAM B-size ball component including handlebar mounts, brake/clutch reservoir bases, U-bolt mounts, and all RAM B-size cradles for phones, GPS units, and cameras.

Compact Short Length: The short arm configuration provides minimal extension from the mounting base, ideal for tight cockpit spaces on sportbikes, small displacement motorcycles, or dashboard installations where a low-profile setup is needed.

Use Case Scenarios

• Phone Navigation Setup: Connect a RAM phone cradle to a handlebar mount on your motorcycle for compact GPS navigation without obstructing instrument clusters on bikes with limited handlebar real estate.
• Action Camera Mounting: Link an action camera ball adapter to a mirror stem base or handlebar clamp for tight, vibration-free POV footage during track days or adventure rides.
• Multi-Device Configurations: Use as part of a dual-mount system alongside medium or long arms to position both a phone and GPS unit at different viewing angles from a single base.

Why Choose the RAM Mounts B Size Short Arm?

• Patented Ball-and-Socket Technology: RAM’s rubber ball and socket system absorbs vibration while allowing infinite viewing angle adjustment – a proven design trusted by military and law enforcement globally.
• Retention Knob Security: Unlike standard RAM arms, the retention knob provides an additional locking mechanism that prevents the arm from loosening during aggressive riding or off-road use.
• Lifetime Warranty: RAM Mounts backs this product with a lifetime warranty against manufacturing defects, reflecting the durability expected from professional-grade mounting hardware.
• Modular Ecosystem Compatibility: Instantly compatible with hundreds of RAM B-size components, allowing you to swap devices, upgrade mounts, or reconfigure your setup without replacing the entire mounting system.

Pros & Considerations

Pros:

• Vibration-resistant retention knob prevents loosening on potholed roads and off-road terrain common across India
• Compact short length keeps devices close to the mounting base, reducing leverage stress and improving aerodynamics
• Universal compatibility with the extensive RAM B-size ecosystem means you can reuse this arm across multiple bikes and device upgrades

Considerations:

• Requires separate RAM B-size ball bases on both connection points (such as a handlebar mount and device cradle), which are sold separately and must be purchased to complete the mounting system
• Short arm length limits viewing angle adjustment range compared to medium or long arms – best for riders who need devices positioned close to the mount rather than extended outward for better visibility

Frequently Asked Questions

Q: What devices is this RAM arm compatible with?

A: This arm is compatible with any RAM B-size ball component. It connects two B-size ball bases together – for example, a RAM handlebar mount to a RAM phone cradle, or a mirror stem base to a GoPro ball adapter. The arm itself is universal; compatibility depends on the cradle/mount you pair it with (phones, GPS units, action cameras, tablets up to the B-size weight limit).

Q: What is the difference between B Size short, medium, and long arms?

A: The difference is the distance between the two socket centers. Short arms (like this model) provide compact, close-to-base positioning ideal for limited space or minimal extension. Medium arms offer moderate reach for standard viewing angles. Long arms provide maximum extension for positioning devices further from the mount or achieving greater angle adjustments. All three use the same 1″ B-size ball system and are interchangeable.

Q: How does the retention knob work on this RAM arm?

A: The retention knob is a secondary locking mechanism located on the arm body. After adjusting your device to the desired viewing angle and tightening the main center knob, you turn the retention knob to apply additional clamping force on the ball-and-socket joint. This extra tension prevents the arm from working loose due to vibration – especially valuable for motorcycle use where engine vibration is constant.

Q: Can this B Size arm be used with RAM A or C size components?

A: No, this arm is only compatible with RAM B-size (1″ ball) components. RAM A-size uses a smaller ball (0.5″) and C-size uses a larger ball (1.5″). The socket diameter is machined specifically for B-size balls. To connect different RAM sizes, you need RAM’s size adapter components, but it’s more practical to use arms matched to your component size.

Q: What is the actual length of this short arm?

A: RAM’s B-size short arms typically measure approximately 1.5″ to 2″ between socket centers, providing minimal extension while still allowing 360-degree rotation and angle adjustment. The compact profile keeps mounted devices low and tight to the base, reducing wind resistance and leverage stress during riding. For precise measurements, RAM’s official specification sheets list exact socket-to-socket dimensions.
