Available Accessories

1. Gravity Phone Holder

A practical smartphone holder for customers who prefer a traditional mechanical phone grip rather than magnetic attachment.

The gravity-style holder supports a compatible smartphone using its gripping structure, providing a convenient mounting option for navigation, vehicle applications or other permitted phone functions.

Ideal for adding a phone to your screen mounting setup without relying on a magnetic phone case or attachment.

Best For: Everyday smartphone mounting with a mechanical grip.

2. Magnetic Phone Holder

A compact magnetic mounting option designed for customers who prefer a cleaner, more streamlined way to position their smartphone.

The magnetic holder allows compatible phones or magnetic mounting accessories to attach to the mounting point, making it convenient to place and remove your device.

Magnetic compatibility depends on your phone, case and mounting accessories. Some devices may require a compatible magnetic case or additional magnetic ring.

Best For: Convenient smartphone placement with magnetic attachment.

3. Sliding Cold Shoe Extension Kit

A modular extension assembly that combines a sliding cold shoe mounting base with an adjustable cold shoe-to-1/4-inch arm.

It provides an additional adjustable mounting connection, allowing compatible equipment or adapters to be positioned away from the main mounting rail.

This is especially useful when you need more flexibility in arranging accessories or connecting equipment that uses a compatible 1/4-inch threaded interface.

Best For: Extending and repositioning compatible equipment away from the main rail.

4. Two-Way Radio Mount

An expansion attachment intended for mounting compatible handheld two-way radios as part of your modular screen setup.

It provides a dedicated mounting option for users who want to organise radio equipment alongside other compatible accessories, rather than leaving it loose around the vehicle interior.

Particularly useful for touring, outdoor activities and communication equipment setups.

Radio compatibility depends on the device's size, mounting arrangement and the holder's attachment interface.

Best For: Mounting compatible handheld two-way radios.

5. Cold Shoe to 1/4" Articulating Arm

An adjustable mounting arm that connects a cold shoe mounting position to a compatible 1/4-inch threaded accessory.

The cold shoe end attaches to a compatible cold shoe slot, while the 1/4-inch threaded end provides a connection point for supported cameras, adapters or other mounting equipment.

Its articulating structure allows the attached accessory to be positioned and angled according to your preferred setup.

This accessory uses an existing cold shoe mounting position rather than creating an additional one.

Best For: Connecting 1/4-inch threaded equipment to an existing cold shoe slot.

6. 1/4" to 1/4" Articulating Arm

A versatile adjustable extension arm designed to connect two compatible components using 1/4-inch threaded mounting interfaces.

It can be used to extend the position of a mounting accessory, create additional clearance or adjust the angle of supported equipment.

Unlike the Cold Shoe to 1/4" Arm, this version is intended for connections between compatible 1/4-inch threaded mounting points rather than attaching directly to a cold shoe slot.

Best For: Extending and adjusting equipment with compatible 1/4-inch connections.

7. Action Camera Mount Adapter Kit

Connect a compatible action camera to your modular mounting setup with this practical adapter kit.

The kit includes a 1/4-inch threaded-to-GoPro-style action camera mounting adapter and a matching thumb screw. It allows cameras with compatible mounting fingers to connect to a suitable 1/4-inch mounting arm.

Suitable for supported GoPro-style action camera mounts and other cameras equipped with a compatible mounting adapter.

Some DJI Osmo Action cameras use magnetic quick-release connections and require a separate compatible quick-release adapter before attaching to this kit.

A compatible 1/4-inch mounting arm is required and is not included with this accessory unless specified separately.

Best For: Connecting compatible GoPro-style action cameras to a 1/4-inch mounting arm.

Which Accessories Do I Need?

For an Additional Smartphone

Choose the Gravity Phone Holder or Magnetic Phone Holder, depending on your preferred phone attachment method.

For an Action Camera

Choose the Action Camera Mount Adapter Kit together with a compatible 1/4-inch mounting arm, unless your existing setup already provides the required connection.

For a Two-Way Radio

Choose the Two-Way Radio Mount and confirm that your radio and mounting arrangement are compatible.

For More Positioning Flexibility

Choose the Sliding Cold Shoe Extension Kit or an appropriate Articulating Arm, depending on the mounting interfaces you need to connect.
