RectorSeal Fortress 4.5" 45° In Vertical Elbow – Gray LD122 Lineset Cover
The RectorSeal Fortress® 4.5" 45° In Vertical Elbow (LD122 – Gray) redirects mini split and HVAC lineset cover duct vertically with a 45-degree inward turn. This fitting is typically used to gradually move the duct and lineset back toward the wall, allowing for controlled, clean routing during installation.
Designed for LD122 (4.5") Fortress duct systems, this vertical elbow is fully compatible with MRCOOL Line Guard kits and other 4.5" lineset cover components. It protects and conceals refrigerant lines, drain hoses, and communication wiring while delivering a professional, finished exterior appearance.
Constructed from heavy-duty, UV-stabilized and fire-resistant PVC, Fortress fittings are tested to over 2,000 hours of UV resistance and operate in temperatures ranging from -4°F to 140°F. The gray finish complements residential and commercial exteriors and can be painted to match surrounding surfaces.
Ideal for MRCOOL DIY mini split systems, ductless heat pumps, and HVAC installations requiring gradual inward vertical routing transitions.
