Audix JBM40 Metal Safety Junction Box

Plenum Rated Metal Junction Box for Ceiling Microphone Installations

The Audix JBM40 is a plenum rated metal safety junction box designed to house connectors and plenum-rated cabling in installed ceiling microphone systems. Built specifically for use with Audix M40 series ceiling microphones, this junction box provides a secure and code-compliant enclosure for wiring connections in commercial and institutional environments. It is an essential accessory for contractors and AV integrators working in spaces that require plenum-rated components.

Designed for Audix M40 Series Ceiling Microphones

The JBM40 is engineered to integrate directly with the Audix M40 series ceiling microphone system. Its dimensions and construction allow it to properly contain and protect microphone wiring connections above the ceiling tile. This compatibility ensures a clean and professional installation while maintaining compliance with building regulations.

Plenum Rated Construction for Code Compliance

In commercial buildings, plenum spaces require approved materials that meet fire safety standards. The JBM40 is constructed as a plenum-rated enclosure, making it suitable for installation in air-handling ceiling spaces where code compliance is mandatory. This ensures that wiring connections remain safely contained within approved materials.

Brass Strain Relief for Secure Cable Management

The junction box features an integrated brass strain relief that secures the outer cable jacket and reduces tension on internal wiring connections. This strain relief helps protect terminations from movement or accidental pulling, improving long-term reliability in permanent installations.

Protects Connectors and Wiring in Installed AV Systems

By enclosing connectors and cable splices inside a durable metal housing, the JBM40 helps prevent damage from environmental exposure or accidental contact above the ceiling. This added protection is particularly important in conference rooms, lecture halls, government facilities, and houses of worship where ceiling microphones are commonly deployed.

Durable Metal Housing for Long-Term Reliability

Constructed from sturdy metal materials, the Audix JBM40 is designed for lasting performance in professional AV installations. Its solid build quality ensures dependable protection of microphone wiring and connectors in fixed infrastructure environments.
