Impact Recovery System’s revolutionary new steel bollard system solves the problems of rigid bollards while retaining the benefits. The SlowStop® Bollard is a revolutionary energy absorbing bollard 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. The post is able to tilt approximately 20° as it progressively absorbs energy, greatly dampening any impact. After impact, the post returns upright, leaving the guard intact and ready to perform again.
