Add protection to people and your facility in order to prevent damage. Create a barrier with Steel Post Bollards by preventing vehicles from entering certain areas. Also, set out in front of exposed equipment, housings and fixtures that may need guarding and prevent vehicle bumps. Post is constructed of 1/4 in thick steel mounted on 3/8 in thick plate with pre-drilled 3/4 in mounting holes to ease installation. They are powder-coated with durable, baked-on safety yellow for visibility. The contrast black high-density polyethylene post cap (included) is removable to fill the post with concrete for added strength and protection.
