Category: Accessory

This adapter frame is the ultimate professional solution for installing your 18 in. wall exhaust fan (sold separately) onto your corrugated metal building. Designed specifically for buildings with ridged panels, this one-piece frame is fabricated from a durable high-density EPS on one side, which molds to the R-panel ridge pattern on your building exterior, allowing you to seal gaps for a more watertight, draft-free, and pest-proof install on your building, as well as an exterior-grade plywood on the other side to provide a flat surface for your exhaust fan to mount. This adapter frame arrives to you fully assembled with the cutout made for proper placement of your fan, and is ready to use with a pre-painted coat of white primer. 

Please note that purchase of this item includes the adapter panel only - exhaust fan sold separately. This frame is compatible with Maxx Air fan models IF18, IF18UPS, IF18R, and IF18RUPS.

Christopher ★★★★★

The four mounting brackets made lining up the frame on my R-panel wall incredibly easy. My 18-inch fan fit snugly and the whole thing took less than twenty minutes to install.

Alexander ★★★★★

The corrugated profile lines up perfectly with my metal building’s ribs, so the frame sits flush without any awkward gaps. It took maybe ten minutes to bolt on, and the fan dropped right in with zero wrestling. Exactly what I needed for a clean, professional install.

Miles C. ★★★★★

I was worried the corrugated profile might make installation tricky, but this frame matched the ridges perfectly and the whole thing took me under 15 minutes.
