INABA DENKO SLIMDUCT BLACK SD-77-K Lineset Cover 1 m
The SLIMDUCT SD-77-K straight duct offers a practical 1 m section for organising and enclosing exposed air conditioning and heat pump pipework. Its compact length is well suited to shorter runs, finishing sections and installation areas where the trunking route needs to be adjusted more precisely.
Refrigerant pipes, drainage and electrical cables can be routed together within the protective duct, helping create an organised and professional HVAC installation. As part of the SLIMDUCT SD trunking system, the SD-77-K works with matching fittings and accessories to continue the route around corners, connections and other changes in the installation layout.
Made from durable UV-resistant PVC, the black decorative lineset cover can be installed indoors or outdoors. Its 75 × 63 mm profile provides space for compatible HVAC service lines while maintaining a compact external appearance.
The duct includes punch-out mounting holes every 100 mm, and concealed screw fixing keeps installation hardware out of sight after the cover is fitted. Additional 1 m or compatible SD-77-K sections can be connected using the SJ-77-K duct coupler when a longer route is needed.

APPLICATIONS
The 1 m SD-77-K decorative lineset cover is ideal where a shorter duct section provides better flexibility, including compact pipe routes, final sections of larger installations and areas where standard 2 m lengths would require unnecessary cutting.
It helps keep insulated refrigerant pipes, condensate drainage, cables and wiring concealed and protected. Used with compatible SLIMDUCT SD fittings, the SD-77-K becomes part of a modular trunking system for residential and commercial air conditioning and heat pump installations.
