This bollard kit is made of a resilient steel parking bollard that is strong enough to eliminate traditional wheel stops. Includes the signpost, HDPE sign, brackets and anchors. Just provide the cement to pour inside of the steel bollard and install it on a cement pad. Forget about damaged sign posts and vehicles! This bollard system is an energy absorbing collision shield that does more than just block access. During a collision, the kinetic energy of the impact is progressively absorbed by an elastomer hidden in the base of the bollard.
