Pathways, supports and pulling horizontal cable
How horizontal cable gets from the telecom room to the outlet without damage: planning the route and length from a floor plan, supporting cable from the structure with J-hooks, trays and conduit, keeping away from power and lighting, pulling within tension and bend limits, leaving slack, and recognizing when ratings and firestopping need attention.

Skills you'll practise
- Estimate a horizontal run's length from a floor plan and check it against the 90 m permanent-link limit
- Choose and install supports (J-hooks, tray, conduit) that hold cable from the building structure without crushing it
- Set up and carry out a pull that stays within the cable's pulling-tension and bend-radius limits
- Identify routes that pass too close to power or lighting, or that rest on the ceiling grid, and correct them
- Recognize when a cable rating or a wall penetration needs to be checked with the lead before work continues
