Expert Insights
Before ordering, measure the outside diameter (OD) of your existing steel post — this 4-inch sleeve has a 4.750-inch inside diameter sized to fit standard 4-inch schedule 40 pipe with a snug, secure fit. Installation requires no tools or fasteners: simply lift the sleeve and slide it down over the top of the bollard until it reaches ground level. The red color follows OSHA safety color standards for marking fire protection equipment, danger zones, and stop/emergency areas, making it a practical choice for fire lanes, hydrant markers, and restricted zones. Built from UV-stabilized LDPE, this sleeve maintains its vibrant red color and structural integrity through prolonged sun exposure, rain, snow, and temperature swings.
