The RectorSeal Fortress® 4.5" Flat Elbow (LD122 – Gray) is designed to redirect mini split and HVAC linesets horizontally along a wall, allowing installers to navigate around obstacles while maintaining a clean, professional exterior appearance.

This flat elbow is part of the Fortress Lineset Cover System and is fully compatible with MRCOOL Line Guard kits and other 4.5" (LD122) duct systems. It provides reliable protection for refrigerant lines, drain hoses, and communication wiring against UV exposure, weather, and physical damage.

Constructed from heavy-duty, UV-stabilized and fire-resistant PVC, Fortress components are tested for over 2,000 hours of durability and built to perform in temperatures ranging from -4°F to 140°F. The gray finish blends seamlessly with modern exteriors and can be painted to match surrounding surfaces.

Ideal for MRCOOL DIY mini split systems, heat pumps, and other ductless HVAC installations where clean wall transitions are required.
