INABA DENKO SLIMDUCT Anthracite Grey SD-77-A Lineset Cover 1 m
The INABA DENKO SLIMDUCT SD-77-A straight duct offers a compact 1 m solution for covering exposed air conditioner and heat pump service lines. The shorter section makes it easier to complete limited pipe runs, finishing sections and installation routes where more precise adaptation of the trunking length is required.
Insulated refrigerant pipes, condensate drainage and electrical cables remain neatly enclosed within the duct, helping protect the services while improving the overall appearance of the installation. The SD-77-A works with compatible components from the SLIMDUCT SD trunking system, allowing the pipe cover route to be adapted with matching elbows, couplers and other fittings.
Its anthracite grey finish makes this decorative lineset cover particularly suitable for darker architectural surfaces where white or ivory trunking may be visually prominent. Durable UV-resistant PVC supports both indoor and outdoor use.
For convenient installation, the straight duct has punch-out fixing holes at 100 mm intervals and concealed screw fixing for a clean exterior finish. Where additional length is needed, adjoining SD-77-A sections can be joined with the SJ-77-A duct coupler.
