SD-77-B INABA DENKO SLIMDUCT SD Lineset Cover 2 m (brown)

INABA DENKO SLIMDUCT SD-77-B Lineset Cover 2 m Brown

The INABA DENKO SLIMDUCT SD-77-B straight duct provides a 2 m protective route for exposed air conditioning and heat pump pipework. It neatly encloses insulated refrigerant pipes, condensate drain lines and electrical services, helping create an organised installation while protecting HVAC lines from external exposure.

Designed to integrate with the SLIMDUCT SD trunking system, the SD-77-B can be combined with matching elbows, connectors and other fittings to build a continuous pipe covering route. The 2 m straight duct is well suited to longer sections of pipework, reducing the number of connections required along straight installation runs.

The brown decorative lineset cover offers a practical alternative where the trunking needs to coordinate with timber-toned, brown or darker building surfaces. Its durable UV-resistant PVC construction makes it suitable for both indoor and outdoor installations.

Punch-out fixing holes at 100 mm intervals simplify mounting, while concealed screw fixing keeps the installation hardware hidden beneath the cover. For routes extending beyond a single section, multiple SD-77-B ducts can be connected using the matching SJ-77-B duct coupler.

DIMENSIONS

APPLICATIONS

The SD-77-B decorative lineset cover provides protective trunking for air conditioning and heat pump installations where refrigerant pipework and associated services need to remain concealed. It is suitable for covering insulated copper refrigerant pipes, condensate drainage, electrical wiring and other compatible HVAC service lines.

Its 2 m length makes the straight duct particularly practical for extended pipe routes where fewer joints are preferred. Together with matching SLIMDUCT SD components, the SD-77-B forms a modular decorative trunking system that can be adapted to residential and commercial HVAC installations.
