Fortress 84037 LWF92I 3.5 Inches Lineset Wall Flange Ivory

Product Description

The Fortress 84037 LWF92I is a 3.5 inch lineset wall flange in Ivory finish, designed to provide a clean, professional transition point where HVAC linesets, refrigerant lines, electrical cables, or drain pipes pass through a wall surface. This injection molded Polypropylene and PVC fitting is a key component of the Fortress prefabricated duct and fitting system, which conceals and protects exposed refrigeration linesets, electrical wiring, and water or drain piping in both residential and commercial HVAC installations. HVAC technicians, installers, and contractors rely on wall flanges like the 84037 to create a finished, code-compliant appearance at lineset penetration points, eliminating exposed gaps that collect debris and moisture. The Fortress system is precision engineered from UV-stabilized Polypropylene and extruded PVC, meeting the requirements of the UL-94V-0 flammability specification. Components are rated for temperatures from -4 to 140 degrees Fahrenheit, making them suitable for year-round outdoor and indoor use in a wide range of climate conditions. The split construction of Fortress fittings is a standout feature for retrofit and new construction work alike. Because each component splits apart, installers can fit the flange around an existing lineset without disconnecting or cutting lines, saving significant time on the job. The Ivory color is one of four standard Fortress colors, including White, Brown, and Gray, chosen to coordinate with common building exterior and interior color schemes. No painting is needed. Internal fixings are incorporated directly into the design, so external mounting brackets are not required. The 84037 wall flange measures 5 inches by 6 inches by approximately 2.125 inches and weighs 0.5 pounds. It ships as a single unit and is manufactured in the USA. This fitting pairs with Fortress lineset cover duct, inside and outside corners, and other system components for a complete, professional lineset cover installation.
