Product Overview
The ASTM K4 Sleeve - Black is a black HDPE sleeve component for ASTM K4 bollard applications. The original product details list 1/4 inch nominal wall thickness, dome-top high-density thermoplastic polyethylene construction, ultraviolet and anti-static additives, and a black color.
Use this when you need the sleeve component rather than a complete crash-rated bollard. Review the Product Details below to confirm material, wall thickness, color, and compatibility with the bollard system before ordering.
