INABA DENKO SLIMDUCT Ivory SK-77-I 90° Elbow
SK-77-I 90° elbow is designed for routing SLIMDUCT SD-77 and NSD-77 lineset covers through a 90° change of direction on a flat surface. It provides a clean and professional transition while keeping air conditioner and heat pump service lines concealed and protected within the decorative trunking system.
Designed for horizontal trunking runs, the SK-77-I allows insulated refrigerant pipes, condensate drain lines and electrical wiring to follow a precise 90° turn along walls, façades and other flat building surfaces. The compact fitting maintains a continuous lineset cover and a neat appearance through the change of direction.
Manufactured from durable UV- and water-resistant PVC, the elbow provides long-term protection against outdoor conditions while remaining suitable for interior installations. The Ivory (RAL 7044) finish coordinates with matching SLIMDUCT ducts and fittings for a consistent finished appearance.
A screw-fixed cover provides secure assembly and convenient access during installation.
