RectorSeal Fortress 4.5" 45° Out Vertical Elbow – Gray LD122 Lineset Cover

The RectorSeal Fortress® 4.5" 45° Out Vertical Elbow (LD122 – Gray) redirects mini split and HVAC lineset cover duct vertically with a 45-degree outward turn. This fitting is typically used to gradually move the duct and lineset away from the wall, offering controlled clearance and installation flexibility.

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 conceals and protects refrigerant lines, drain hoses, and communication wiring while maintaining a clean, professional exterior finish.

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 outward vertical routing transitions.
