Bulletpoint Carbon Fiber Dash Mount Arm 4.7" – Matte Black, 20mm Dual-Socket, Tool-Free Thumbscrews

A lightweight, stiff 4.7-inch matte black carbon fiber mounting arm that links 20mm ball mounts to phone and device holders for stable in-vehicle positioning. This Bulletpoint Mounting Solutions Dash Mount 4.7" Arm is engineered to combine aircraft-style carbon fiber strength with simple, tool-free adjustability so you can place smartphones and other devices where you need them most. At 4.7 inches overall (4 cm arm length), the assembly uses dual aluminum 20mm sockets and plastic thumbscrews to connect to any compatible 20mm ball base—whether Bulletpoint's dash mounts or many third-party systems. The matte black finish keeps a low-profile look while resisting everyday wear.

How does this arm attach to my existing dash mount?

Attachment is quick and mechanical: slide a 20mm aluminum socket over the ball on your mount and secure it with the integrated thumbscrew. Both ends of the arm accept 20mm balls, so you can link a base and a device mount without adapters.

• Dual 20mm aluminum sockets fit standard 0.787" ball mounts
• Plastic thumbscrews tighten by hand—no tools required
• Quick-connect design for fast installation or removal

Will it hold my phone steady over bumps and turns?

The carbon fiber arm provides a very favorable stiffness-to-weight ratio, helping resist flex and vibration compared with plastic arms. Stability ultimately depends on the base and device holder used, but the dual-socket design delivers a secure link between a heavy-duty base and your phone mount.

• Carbon fiber construction for low flex under load
• Aluminum sockets provide a rigid connection to 20mm balls
• Thumbscrews lock socket position once adjusted

How adjustable is the arm for viewing angle and placement?

With two 20mm ball sockets you get a wide range of tilt, swivel and rotation options by unlocking the thumbscrews, repositioning, then retightening. The short 4 cm arm is ideal when you want to reduce reach and keep the device close to the dash for ergonomic viewing.

• Two ball joints allow compound adjustment across multiple axes
• Short length minimizes device reach into cabin space
• Thumbscrews enable quick micro-adjustments while driving (stopped)

What are the size and material specifics I should know?

The overall assembly measures 4.7 inches (12 cm) end-to-end; the carbon fiber arm without connectors measures 1.57 inches (4 cm). Connectors are machined aluminum with integrated plastic thumbscrews, and the arm's matte black finish reduces glare and visible wear.

• Overall length: 4.7 in (12 cm); arm only: 1.57 in (4 cm)
• Carbon fiber arm for strength and low weight
• Aluminum 20mm sockets compatible with standard 0.787" balls

Who is this for? This Bulletpoint 4.7" Matte Black Carbon Fiber Arm is aimed at drivers and professionals who want a compact, strong linkage between a 20mm-ball dash base and a device holder—motorists who value low weight, reduced flex and a discreet black aesthetic. It's well suited for in-vehicle phone mounting, GPS rigs, handheld radio connectors and any setup where a short, rigid arm improves sightlines and reduces clutter. If you already own a 20mm ball mount and want a durable, quick-adjust solution that won’t add much weight or visual bulk, this arm is a practical upgrade.
