The black line set cover kit hides copper pipework, wiring and drainage in a slim black PVC channel that reads as a deliberate design line rather than a service pipe. It is the natural choice for dark facades, anthracite window frames, metal cladding and commercial storefronts where a white trunking would stand out.
| Component | Function |
|---|---|
| Straight Duct | The main trunking section that runs along the wall, carrying the refrigerant pipes, cables and condensate drain. |
| Coupling (Straight Connector) | Joins two straight duct sections end to end for longer runs. |
| Reducer Coupling | Connects duct sections of different profile widths on stepped installations. |
| 90 Degree Flat Elbow | Turns the duct line left or right within the wall plane. |
| Wall Entry Cap | Finishes the point where the line set enters the wall, hiding the penetration neatly. |
| 90 Degree Vertical Elbow | Turns the run from the wall down to a ground-level outdoor unit. |
| Adjustable Elbow | Swivel joint that covers angled turns between 0 and 90 degrees. |
| 45 Degree Flat Bend | Softens direction changes on angled facades and gutter lines. |
| 90 Degree Vertical Bend | Routes the trunking over obstacles in the vertical plane. |
| Side Entry Elbow | Guides the line set into the unit connection from the side. |

Q: Does the black cover overheat in direct sunlight?
A: No. The profile is moulded from UV-stabilised rigid PVC and its purpose is to shield the line set from sun exposure. The black formulation is the standard colour used on south-facing and high-sun installations.
Q: Is black suitable for commercial buildings?
A: Yes. Black is widely used on shopfronts, offices and modern residential facades where the trunking should match dark window frames and cladding.
Q: What colours are available in this series?
A: The series is produced in white, black, brown and ivory, all sharing the same profile sizes and component range so colours can be mixed within one project.
