INABA DENKO SLIMDUCT Anthracite Grey SD-77-A Lineset Cover 2 m
The INABA DENKO SLIMDUCT SD-77-A straight duct provides a 2 m covering section for routing air conditioning and heat pump service lines along walls, ceilings, floors and building façades. It keeps insulated refrigerant pipes, condensate drainage and electrical wiring enclosed within a protective duct while creating a clean, coordinated finish.
The SD-77-A is part of the modular SLIMDUCT SD trunking system, allowing straight sections to be combined with compatible couplers, elbows and other fittings. Its 2 m length is particularly practical for extended pipe routes, helping cover longer sections with fewer joints while retaining flexibility to adapt the trunking around changes in the installation layout.
Manufactured from durable UV-resistant PVC, the anthracite grey decorative lineset cover is suitable for indoor and outdoor applications. The dark grey finish provides a modern alternative for installations where the trunking needs to coordinate with darker façades, frames or architectural surfaces.
Punch-out mounting holes positioned every 100 mm simplify fixing, while the concealed screw design keeps fasteners hidden after installation. Additional SD-77-A sections can be connected with the matching SJ-77-A duct coupler where the straight trunking route extends beyond 2 m.
CLEAN AND PROFESSIONAL INSTALLATION

The INABA DENKO SLIMDUCT SD trunking system combines straight lineset covers with a wide range of fittings to conceal, protect and neatly organise exposed refrigerant pipework in split air conditioner installations.
