The patented SlowStop® guarding system is a revolutionary rebounding steel pipe energy absorption system 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, softening the impact. After the impact, the post returns upright, leaving your guard intact and ready to perform again. SlowStop® bollards are designed to never create damage to your concrete foundation.

The system is made up of four main components: The post (standard schedule 40 / ISO pipe or equivalent), the base, an adapter, and the energy absorbing elastomer. Each piece is modular and easily replaced should damage occur. The system is installed using four to eight concrete anchor screws to secure the unit to the concrete.

The benefits of the system are numerous. Among them are the following:

  • 01

    Your concrete foundation will never be harmed.

  • 02

    Installation is simple, requiring only common tools and taking about 15 minutes per standard bollard.

  • 03

    Vehicle occupants are less likely to be injured as impacts are gradually softened.

  • 04

    Damage is reduced to both the vehicle and the bollard during impact.

  • 05

    Fork Truck loads are less likely to be lost during an accidental collision.

  • 06

    The modular system allows for the replacement of damaged parts without completely re-pouring concrete.

  • 07

    Flexible relocation without filling large core holes and chipping away old concrete.

  • 08

    Fencing and complex barriers can be created from slide-together connectors without the need for welding.


SlowStop® was invented in Belgium by the same inventors as the Hercules Bollard. Hercules was a successful product that also allowed a bollard to tilt when impacted, but it was complicated and expensive. Formerly known in Europe as SoftStop®, the SlowStop® Bollard has been extensively tested by testing firm TÜV Rheinland TNO and is proven through a large installation base. With worldwide patents and patents pending,the SlowStop® Bollard is now available worldwide exclusively from SlowStop Guarding Systems, LLC and its distributors. Its product line-up has been expanded to provide a wide range of industrial guarding such as guardrail, corner protection, rack end guard, and column protection.

SlowStop’s technology is patented in many places around the world:
