The brown line set cover kit, known in the UK and Europe as air conditioning pipe trunking, encloses the line set of a split system in a wood-tone brown channel. It is specified wherever the wall material is brick, timber cladding or render in earth tones, because the trunking disappears against the masonry instead of cutting across it.
| 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: Will brown match brickwork?
A: The brown tone was selected to sit naturally beside common red-brown brick, timber cladding and terracotta detailing. On most masonry facades the trunking reads as part of the wall.
Q: Is this the same as air conditioning trunking sold in the UK?
A: Yes. It is the same product category: in the UK it is searched and sold as air conditioning pipe trunking, while North American buyers know it as a line set cover.
Q: How is the trunking fixed to the wall?
A: The base channel is screwed to the wall at set intervals, the line set is laid in, and the snap-on cover closes over it. Joints and corners are covered by the matching fittings in this kit.
