Product Overview

The 8-Inch Round 57-Inch Yellow Smooth Post Sleeve (SKU: A1737E) is a large-diameter decorative bollard cover that slides over existing 8-inch steel posts, converting bare metal into a clean, high-visibility yellow safety marker.

With an inside diameter of 8.875 inches and an outside diameter of 9.375 inches, it stands 57 inches tall and weighs approximately 10 lbs. The yellow color meets OSHA standards for marking caution zones, physical hazards, and pedestrian safety areas, making it ideal for large-post applications in parking garages, distribution centers, and commercial properties.

Expert Insights

Accurate measurement is essential for the 8-inch size — measure the outside diameter (OD) of your existing post and confirm it falls within the 8.875-inch inside diameter of this sleeve, which is designed to fit standard 8-inch schedule 40 pipe (8.625-inch OD). Installation is the same as all smooth post sleeves: slide it over the top of the bollard until it rests at ground level, with no tools, fasteners, or adhesives required. Note that the 8-inch models stand 57 inches tall (one inch taller than the 4-inch and 6-inch versions), providing slightly more coverage for taller bollard installations. Yellow is the OSHA-standard color for caution, physical hazards, and tripping risks, and the UV-stabilized LDPE ensures long-term color retention and weather resistance in any climate.
