Bulletpoint Dash Mount Arm 4.7" Matte Black Carbon Fibre — 20mm Dual‑Socket, Lightweight Secure Positioning

The Bulletpoint Mounting Solutions 4.7" Matte Black Carbon Fiber Dash Mount Arm is a lightweight, durable dual-socket mounting arm that connects to 20mm ball mounts to position smartphones and similar devices securely on vehicle dashboards.

This compact mounting arm combines carbon fiber strength with aluminum socket ends to deliver a dependable, low-profile way to place phone holders, GPS units, radios or other accessories exactly where you need them. At just 4.7 inches overall (4.0 cm for the arm section) it’s designed for minimal visual impact while still providing flexible adjustability through integrated thumbscrews and standard 20mm compatibility.

How does this arm attach to my existing mount or phone holder?

Attachment is simple: each end has an aluminum dual-socket that slips over a 20mm ball and locks in place with a thumbscrew. That standard socket size is common across Bulletpoint bases and many third-party systems, making it easy to add this arm to an existing setup.

• Dual 20mm socket ends fit 0.787" ball mounts.
• Aluminum connectors for secure, wear-resistant contact.
• Plastic thumbscrews allow hand-tightening—no tools required.
• Quick-connect design: slide over ball and tighten.

Will this arm hold my phone steady over rough roads?

The arm’s carbon fiber construction provides a high strength-to-weight ratio for stability without excess mass. While final steadiness depends on the connected device holder and base, the rigid arm and metal socket ends reduce flex and keep devices more secure than cheap plastic arms.

• Carbon fiber body minimizes flex and adds tensile strength.
• Aluminum socket ends resist deformation under load.
• Dual-socket design distributes forces between two connection points.
• Thumbscrews maintain clamp pressure to prevent slip during motion.

What sizes and dimensions should I expect?

The overall assembly measures 4.7 inches (12 cm) from end to end. The exposed carbon fiber arm section—the portion between the connectors—is 1.57 inches (4 cm), giving a short, compact reach ideal for keeping devices close to the dash without obstructing sightlines.

• Total length: 4.7 inches / 12 cm.
• Carbon fiber arm section length: 1.57 inches / 4 cm.
• Socket size: 20mm (0.787 inches) standard ball fit.
• Finish: matte black carbon fiber for low reflectivity and discreet appearance.

How easy is it to install and adjust in daily use?

Installation and angle adjustments are designed to be tool-free and quick. Each connector uses a thumbscrew that you tighten by hand to lock the arm onto the ball, then loosen to reposition tilt or swivel. This makes in-vehicle adjustments fast and practical during routine use.

• Tool-free installation via integrated thumbscrews.
• Fast repositioning: loosen, pivot, re-tighten.
• Compact profile reduces interference with dash controls.
• Matte finish minimizes glare while driving.

Who is this for: drivers, fleet operators, technicians and outdoor enthusiasts who want a professional, low-profile mounting solution that balances weight and strength. It’s tailored for anyone already using Bulletpoint 20mm ball mounts or who wants to upgrade a mixed-brand mount system to a durable carbon-fiber arm. Ideal when you need a short, rigid link between a base and a device holder without adding bulk or visual distraction.
