2.5 inch Mild Steel Rain Cap

The 2.5 inch mild steel exhaust rain cap provides reliable weather protection for 2.5 inch (64mm) bore vertical exhaust stacks in sheltered and indoor environments. The gravity-operated hinged cap fits directly over the top of the exhaust stack outlet, closing under its own weight when the engine is off to prevent rainwater, leaves, insects and other debris from entering the system. When the engine runs, exhaust gas pressure lifts the cap open freely, allowing unrestricted exhaust flow without any back pressure effect. The mild steel construction delivers cost-effective performance in low-moisture environments such as generator rooms, covered plant bays and warehouse forklift fleets.
