4.5 inch Stainless Steel Rain Cap

The 4.5 inch stainless steel exhaust rain cap is specified for outdoor industrial applications where the exhaust stack bore falls in the 114-115mm range. This size is found on high-capacity generator sets, large industrial fixed plant and heavy crushing and screening equipment where the exhaust outlet exceeds the standard 4 inch but is below the 5 inch range. The stainless steel construction provides excellent corrosion resistance in outdoor and weathered environments, significantly extending service life compared to mild steel alternatives and reducing the frequency of cap replacement on permanently outdoor-installed plant. The gravity-operated hinged cap requires no maintenance and provides reliable automatic weather protection throughout its service life.
