Installing the adapter on the terminal box

To use a terminal box installation adapter, mount the box securely, pass cables through the adapter components, and tighten the grommet and thread to ensure a sealed and stable connection.Tools and Materials Needed
  • Terminal box with pre-installed adapters
  • Screwdriver (typically pan head)
  • Drill and appropriate drill bits
  • Dowels and screws for wall mounting
  • Hammer
  • Cable cutters and strippers
  • Cleaning agent (for fiber optic cables, if applicable)
  • Gloves to prevent contamination
Step-by-Step Installation

1. Mount the Terminal Box Open the terminal box using a screwdriver and place it on the designated wall location. Mark the positions for drilling through the pre-identified holes. Drill the holes, insert dowels with a hammer, and secure the box with screws until tight ( ). 2. Prepare the Input and Output Ports Identify the input port (usually bottom right) and output port (bottom left). Each port has three components: the base, the grommet, and the thread. Pierce the thin membrane in the grommet to allow cable passage ( ). 3. Insert the Cable Through the Adapter

  • Pass the cable through the thread first, then the grommet, and finally into the base of the terminal box.
  • Insert the grommet into the base and screw the thread into the base until the cable is tightly secured and the grommet conforms to the cable shape ( ). 4. Strip and Connect the Cable Once enough cable is inside the terminal box, strip it to expose the strength member and loose tube (for fiber optic cables). Connect the indoor/outdoor assembly, such as a jumper or pigtail, to complete the connection ( ). 5. Secure the Output Cable Repeat the same process for the output port: pass the cable through the thread, grommet, and base, then screw the thread to secure the grommet and cable ( ). 6. Label and Finalize Label the terminal box and cables for easy identification. Ensure all connections are tight, and the box is properly sealed to prevent dust or moisture ingress ( ).
Tips for a Reliable Installation
  • Always wear gloves when handling fiber optic cables to avoid contamination.
  • Use a cleaning agent to clean cable ends and adapters before connection.
  • Verify that the cable is not twisted or bent sharply inside the box.
  • For electrical terminal boxes, ensure power is off before connecting or disconnecting wires ( ). Following these steps ensures a secure, sealed, and properly connected terminal box installation using the adapter, whether for fiber optic or electrical applications.
