Abstract
A bollard assembly is disclosed that includes an elongate hollow bollard having opposed first and second ends, a sidewall extending between the first and second ends, and through hole formed in the side wall. The assembly also includes a sleeve configured to receive and support a lower portion of the bollard, and a hollow cylindrical insert disposed within the lower end of the bollard. A pin protrudes outward from the insert sidewall, extends through the bollard through hole and engages the sleeve, whereby the assembly is retained in an assembled configuration. The bollard includes a prescribed breakaway line along which an upper portion of the bollard can be separated from the lower portion upon sufficient impact. Once the upper portion is broken away, the insert permits the lower portion of the bollard to be removed from the sleeve and replaced with a replacement bollard.
