12 inch Stainless Steel Rain Cap

The 12 inch stainless steel exhaust rain cap is a premium specialist component for 12 inch (305mm) bore vertical exhaust stacks serving the very largest industrial plant and power generation installations. At this scale, only stainless steel is practical for any outdoor application — the large surface area of a 12 inch cap, combined with permanent outdoor exposure, makes mild steel an unsuitable long-term choice. The stainless steel construction provides corrosion resistance and long service life in all outdoor conditions, including coastal, quarry, agricultural and industrial environments. The gravity-operated hinged design provides fully automatic weather protection with no maintenance requirement — important on large installations where access to the top of a tall exhaust stack for routine cap maintenance is not practical. This is one of the rarest stock sizes in the UK industrial exhaust accessories market.
