3M PELTOR ARC Left & Right Side Attachments – Helmet Rail Adapter Kit for FAST System

Overview

The 3M PELTOR ARC Adapters are a Left & Right Side Attachment Kit designed to attach PELTOR ARC headsets to compatible helmet rails using the FAST Helmet Rail Connection system. This modular setup aims to streamline your comms on demanding environments while preserving comfort and fit as you move.

Designed for rugged use, the kit integrates with existing gear to help you stay oriented and connected without sacrificing mobility. While the system is not intrinsically safe and is intended for industrial or military tactical settings, it can be a practical upgrade for teams that rely on reliable headset integration with their helmets.

Enhanced comfort and fit

One of the primary goals of the ARC adapters is to minimize pressure points from the headband, helping to reduce hot spots where the headset bears weight. The result can be a more comfortable wear over extended operations, enabling you to focus on the task at hand rather than discomfort.

• Reduces potential pressure points along the headband for a more comfortable fit
• Long-term wearability without constant readjustment

Secure mounting and compatibility

The kit provides left and right guide arm attachments that clamp to helmet rails, enabling a secure mounting of the headset to a FAST system. This rail attachment design supports quick setup and consistent alignment with your gear, helping maintain situational awareness during action.

• Rail system attachment for helmet rails
• Left and right guide arm attachments for balanced support
• Conversation kit compatible with the FAST Helmet Rail Connection system
• Not intrinsically safe; intended for industrial/occupational use only

Real-world usage and considerations

In field or shop environments, teams can benefit from an adaptable interface that respects helmet geometry while preserving access to comms hardware. The design supports modular integration with existing PELTOR ARC gear and is geared toward tactical or industrial workflows where reliable headset mounting matters more than aesthetics.

What you get

The Left & Right Side Attachment Kit serves as a conversation-ready upgrade to fit the FAST Helmet Rail Connection system, offering a practical path to enhance compatibility between headsets and protective headgear without replacing your entire setup.
