Fortress 4.5" End Fitting – LEN122W (White) | Lineset Cover Termination | MRCOOL Compatible

The Fortress 4.5" End Fitting (LEN122W) provides a clean, professional termination point for outdoor HVAC lineset cover installations. Designed to cap and seal the open end of a lineset duct run, this fitting helps prevent debris, pests, and moisture from entering the ducting—protecting your refrigerant lines, wiring, and drain tubing.

Built for the Fortress LD122 Series, this 4.5" end fitting is fully compatible and interchangeable with MRCOOL® LineGuard, making it an excellent choice for mini-split systems, heat pumps, and central A/C installations. Whether used at the condensing unit or at the end of an extended cover run, the LEN122W ensures a polished, finished appearance.

Made in the USA and constructed from UV-stabilized, weather-resistant PVC, this end fitting offers long-term durability in harsh outdoor environments. Its white finish is also paintable, allowing you to match siding, trim, stucco, or commercial building surfaces.
