Eagle 8" Red Smooth Bumper Post Sleeves make old bollard posts look like new with no need to paint and scrape. The red high density polyethylene (HDPE) construction with UV inhibitors resist fading, rusting or cracking. Eliminates annual maintenance while helping to protect vehicles and the post from impact damage. Have an easy slide-on installation. Sleeves can be trimmed for an exact fit. (Sleeves are available to fit 4", 6" and 8" NPT pipe sizes. Also available in yellow, white and blue).
