What a complete FOS system includes and how it protects crowds and performers.
A Front-of-Stage (FOS) system is a complete, engineered assembly of concert barriers and related components that forms the primary safety structure between the crowd and the stage. It is more than just a barricade line — it is a system of straight panels, corners, doors, cable modules, and security positions designed to work together under load.
Every FOS system is configured to match stage geometry, crowd size, and event risk profile.

Core Components of a FOS System
- Straight barriers (steel or aluminum)
- Inside and outside corners, plus adjustable versa corners
- Door modules for crew and emergency access
- Cable pass-through sections
- Optional security steps or platforms
- Transport and storage carts
Why Use a System Approach?
- Ensures compatibility between all components
- Improves overall structural integrity under crowd pressure
- Simplifies planning and repeatable deployments
- Reduces risk by following proven configurations
