Bulletpoint Mounting Solutions Extension Arm 8"-10.5" Carbon Fiber + Kevlar Telescoping Dual Socket Fits 20mm Attachment Ball
Quick take
This telescoping extension arm lets you adjust the distance between your dash mount and your device holder, extending from 8 inches to 10.5 inches and locking in place with a collar. It uses dual 20mm ball style connections, making it a convenient upgrade if you run compatible 20mm mounts and want a more rigid feel. The main caveat is fitment, you need a 20mm ball ecosystem to make the arm work with your current hardware.
Pros and cons
Pros
- Adjustable telescoping length (8 to 10.5 inches) for dialing in placement.
- Carbon fiber and Kevlar construction aimed at staying lightweight while feeling sturdy.
- Dual 20mm aluminum connector ends for compatibility with 20mm ball mounts.
- Thumbscrew style controls make it faster to attach and adjust.
Cons
- Not a complete mount by itself, you still need compatible 20mm dash and device holders.
- No water resistance rating, so you should avoid exposure to rain or water spray.
- Because it connects into an existing mounting system, best results depend on how tightly everything is secured.
What buyers think
Buyer-review evidence for this extension arm is relatively limited in volume, but the recurring themes are consistent. Multiple reviews describe the arm as sturdy and well-built, with a quality fit and finish that feels appropriate for daily driving. There is also feedback focused on real-world stability, with buyers emphasizing that it holds position rather than loosening or wobbling when driving on rougher roads. A couple of reviews also stress the practical tip to tighten the connections enough for a solid setup. Overall, the evidence points to a mount accessory that improves perceived rigidity and adjustability, assuming you have compatible 20mm ball hardware.
How the telescoping extension arm helps your setup
The core job of an extension arm is simple, it changes where your device ends up relative to your dash mount. This model stretches from 8 inches to 10.5 inches total length using a telescoping design, then locks with a center collar you can twist to secure. In day-to-day use, that extra range can matter for driver comfort, cable routing, screen visibility, and keeping the device positioned where you can reach it easily without blocking airflow vents or controls.
20mm ball compatibility you should double-check first
This arm is built for a 20mm mounting system, with dual 20mm aluminum connector ends. Practically, that means it can connect between a compatible 20mm dash mount or base and a compatible 20mm ball device holder. If your current mount uses a different ball size or a different connector style, this accessory may not provide the connection you need. Before ordering, confirm your existing hardware is 20mm ball style and measure the mount spacing needs you are trying to solve.
Build quality: carbon fiber and Kevlar with aluminum ends
The combination of carbon fiber and Kevlar in the telescoping arms targets a blend of lightweight feel and durability. Aluminum connector ends are used at the attachment points, which matters because most stress concentrates near where the mount tightens and locks. In plain terms, if you are tired of flimsy extension links that feel cheap or flex under road vibration, this design is intended to feel more “solid link” between components.
Pros and buyer fit scenarios
Best for
- Drivers who want adjustable device placement between a dash mount and phone or tablet holder.
- People using a 20mm ball mounting ecosystem and looking for a sturdier connection point.
- Anyone who drives on uneven roads or wants to reduce wobble during movement.
You may want to skip it if
- You do not already have compatible 20mm ball mounts or holders.
- Your setup needs a water resistant accessory, this arm is not rated for water resistance.
- You want a single-box complete mounting solution, since this is an extension link rather than a full dashboard mount kit.
Setup and getting a stable feel
Several buyers highlight that stability depends on securing the connections properly. Use the thumbscrew-equipped attachment points to lock things down fully, then test movement gently before you drive. If you feel any looseness, re-check that the collar is fully locked at your chosen length and that each end is tightened enough for your particular device holder weight and leverage.
Alternatives to consider (based on what you need)
If your priority is different from adjustable reach or stiffness, consider shopping by connection type and adjustability first:
- Different-length extension arms: If 8 to 10.5 inches is too short or too long for your dashboard layout, another length range can prevent awkward screen angles.
- Non-telescoping fixed arms: If you know the exact placement you want, a fixed arm can be simpler and reduce adjustment time.
- Different connector standards: If your existing setup is not 20mm ball based, switching to a compatible mount system may be the more straightforward path than forcing an adapter.
Verdict
The Bulletpoint Mounting Solutions extension arm is a strong match for shoppers who already use a 20mm ball mounting ecosystem and want more control over device placement, with a build that focuses on rigidity. It is not a standalone mount, so compatibility is the deciding factor. If your main pain point is wobble, weak-looking connection links, or limited reach, this telescoping carbon fiber and Kevlar arm is built to address that, as long as you tighten and lock it properly.
