Expert Insights
When selecting a smooth post sleeve, always measure the outside diameter (OD) of your existing steel post to ensure a proper fit — this 4-inch sleeve has a 4.750-inch inside diameter designed to accommodate standard 4-inch schedule 40 pipe. Installation is straightforward: simply slide the sleeve down over the top of the bollard until it rests at ground level, with no tools or adhesives required. The yellow color meets OSHA guidelines for marking caution areas, physical hazards, and stumbling/falling risks, making it the go-to choice for parking lots, warehouse aisles, and loading docks. The UV-stabilized LDPE construction ensures the color stays vibrant and the material remains intact through years of sun exposure, rain, and temperature extremes.
