Overview
The Appleton FSK-WR1 is a single receptacle wet location cover engineered for demanding outdoor and damp environment applications. Manufactured from diecast copper-free aluminum with an epoxy powder coat finish, this cover meets NEMA 3R requirements and delivers reliable protection against moisture and environmental contaminants. Wet location receptacle covers provide a gasket that sets around the plug to seal out moisture even when the receptacle is in use. The FSK-WR1 is ideal for industrial facilities, commercial buildings, marine applications, and any setting where electrical receptacles must remain protected from water exposure.
