2.5 Inch 304 Stainless Steel Diesel Generator Exhaust Rain Cap

The gravity counterweight flapper opens automatically under exhaust pressure when the engine runs, bringing unobstructed exhaust flow and no power loss. Once the equipment shuts down, the flap closes by its own weight instantly. It effectively blocks rain, snow, leaves, dust and small animals from entering the muffler and exhaust pipe, avoiding internal water accumulation, rust and blockage.
