A forklift or delivery truck can clip a corner and cause damage that costs more than the delivery was worth. These yellow steel safety bollards stand between the vehicle and what it should not hit. Each post is fabricated from carbon steel with a 4.5-inch diameter and a bright yellow finish that stays visible in rain, glare, and low light. A reflective tape stripe adds an extra layer of visibility when headlights sweep across the surface at night.The six-pack of 42-inch bollards is suited for securing longer perimeters, protecting multiple entry points, or creating a barrier around machinery and racking corners. Each bollard has a pre-drilled base plate and comes with four heavy-duty anchor bolts. Bolt them to concrete for permanent installation that stays firmly in place under impact. When access is needed—for seasonal events, construction, or equipment relocation—simply remove the bolts and temporarily detach the bollards without damaging the base.The carbon steel body transfers impact force into the concrete instead of folding at the weld. Use these bollards to guard storefronts, parking spaces, fueling stations, HVAC equipment, and any surface a vehicle should not touch. Periodically check the bolts and reflective tape for wear, and tighten any loose hardware as needed. Do not install bollards in areas where vehicles travel at speeds that exceed the rated impact resistance of the post. When drilling into concrete, always wear appropriate eye and respiratory protection.
