The Cummins weather-protective inverter generator cover works with Onan P4500i, P4500iDF, P5000iDF EFI generators (not compatible with P2500i). The cover protects your generator from water ingress during harsh weather conditions such as rain and snow while not interfering with portability. It can withstand blowing rain up to 70 mph (113kph) and snow loads up to 18 inches. Setup takes minutes with the included installation manual.
