Fortress 4.5" Wall Flange – LWF122W (White) | Lineset Cover Trim Plate | MRCOOL Compatible
The Fortress 4.5" Wall Flange – LWF122W provides a clean, finished look where HVAC linesets penetrate a wall surface. This trim plate covers the transition between the wall and the lineset cover ducting, helping to conceal gaps, rough openings, and drill-through holes for a neat, professional appearance.
Designed for the Fortress LD122 (4.5") Series, this wall flange is fully compatible and interchangeable with MRCOOL® LineGuard and most major lineset cover systems. It can be used indoors or outdoors, making it ideal for mini-split installations, heat pumps, and central A/C systems.
Manufactured from UV-stabilized, weather-resistant PVC, the LWF122W is built for long-term durability in harsh outdoor environments. Its paintable white finish allows complete customization to match siding, trim, stucco, or interior walls.
Whether you’re a contractor or a DIY installer, the wall flange ensures your system has a polished, secure termination point that protects against pests, debris, and moisture intrusion.
