Fiber Optic Cable Junction Box Tunnel Fixing Clip

Fiber optic cable fixing clips are specialized supports designed to secure cables in junction boxes, tunnels, and other installations while maintaining bend radius and complying with fire and safety standards.

Types of Fiber Optic Clips

Metal and fire-resistant clips are recommended for tunnel and indoor installations, as they comply with BS6701:2016 + A1:2017 and BS7671:18th Edition, which require all cables to be supported by metal fixings rather than plastic or glue-based solutions . Firefly Push Grip Clips, for example, are corrosion-resistant, quick to install, and designed to be nearly invisible once mounted . Clips are available in sizes to support cable diameters from 0.9mm to 3.0mm, with larger sizes in development . Plastic or spring steel clips are also available for lighter applications, such as ceiling or wall-mounted cable runs. Options include nail-in, hammer-on, or threaded rod clips, which can secure cables to beams, flanges, or junction box surfaces .

Installation Considerations

• Bend radius maintenance: Clips should support the cable without sharp bends to prevent signal loss or fiber damage .
• Compatibility with junction boxes: Clips can be used inside fiber optic junction boxes or splice closures to organize and secure pigtails, drop cables, and spliced fibers .
• Fastening methods: Clips can be attached using concrete screws, nails, or hammer-on methods depending on the surface and load requirements .
• Fire safety: In tunnels or enclosed spaces, fire-resistant metal clips are preferred to prevent melting or collapse during high temperatures .

Applications

• Tunnel installations: Secure fiber optic cables along walls or ceilings while maintaining proper spacing and bend radius.
• Junction boxes and splice closures: Organize and fix cables inside FIMP XL, FOSC™400, or other terminal boxes for splicing and distribution .
• Indoor cable management: Support small signal, CCTV, or alarm cables alongside fiber optic cables using the same clip systems .
