The RectorSeal Fortress® 4.5" Tee (LD122 – Gray) allows you to split your lineset cover duct into two directions, providing flexibility for complex mini split and HVAC exterior routing layouts.

Designed for use with LD122 (4.5") Fortress components, this tee fitting is fully compatible with MRCOOL Line Guard kits and other 4.5" lineset cover systems. It protects and conceals refrigerant lines, drain hoses, and communication wiring while maintaining a clean, professional exterior appearance.
