Fiberglass Elbow 12″
The 12″ fiberglass-reinforced plastic elbow is specifically designed to be used as a weatherhood that adapts to many fans. Plastic elbows replace many outdated or corroded metal hoods with smooth, non-porous Osborne RTM-Glas construction. Fits 12″ Osborne Slant Wall fans.
Osborne fiberglass elbows do not become brittle in cold, like other plastics do, and does not heat-sag in hot temperatures.
