Fixed and removable bollards are designed to restrict vehicle access while allowing pedestrians and bicycles to pass through freely. The Mantis Series Fixed Bollards are another forward thinking solution from Heald. Like the Fixed Raptor, they’re designed for locations where anti-ram security is essential but where standard bollard foundations are not practical or permissible. The Mantis also offers its own unique architectural shape and a choice of higher-level crash ratings.

Design Features

Mantis Fixed Bollards offer a unique combination of contemporary style to enhance architectural appeal and an imposing presence to deter potential threats. While boasting higher crash ratings than the Fixed Raptor, the Mantis Series still features shallow excavation depths of just 10” (250 mm) for the Mantis 64 and 12” (300 mm) for the Mantis 80. And like the Fixed Raptor, each model was crash tested as a single unit, so they can be installed as a stand-alone bollard or as part of an array of multiple units.

Mantis Bollards consist of a rectangular shaped element that extends 43” (1100 mm) high and 8” (200 mm) wide for the Mantis 64 or 44” (1112 mm) high and 8” (190 mm) wide for the Mantis 80. The element is anchored below-grade by a structural frame designed to withstand a large impact. The foundations for both models are very compact, and because the structural frames incorporate factory-provided rebar, there is no need for additional rebar mats to be supplied and built onsite. The Mantis series bollards are ideal for the following conditions:

  • Minimal excavation –where underground utilities, high water tables or other site conditions restrict excavation
  • Pedestrian and bicycle access – non-vehicular traffic can move through freely
  • High speed impacts – where the roadway layout allows vehicles to reach higher speeds
  • Minimal setbacks – where critical assets or equipment are in close proximity to entrances (urban applications) and a high level of security is required, regardless of potential vehicle speed
  • Architectural appeal – clean lines of the available bollard covers complement building elements
  • Low impact security presence – since bollards are commonly used, they blend in well with the surrounding streetscape and do not raise awareness to high security measures



Mantis Fixed Bollards are a great alternative to standard bollards. Because they provide a crash tested security rating with only 1 unit, they can potentially be used to block wider areas than standard fixed bollards, which typically are crash tested in groups of 3 units on 36” centers. The shallow mount foundation makes them a perfect choice where bollards are desired, but site conditions do not permit deep excavation. The XL-2500 and XL-2600 are ideal for facilities located in urban settings such as courthouses, embassies, museums, banks, corporate offices, universities, mass transit facilities and parks.

Technical Data

The beauty of Mantis Bollards goes far beyond their contemporary style and single-unit crash-tested rating. The unique shallow mount installation depths of 10” (250 mm) deep for the Mantis 64 and 12” (300 mm) for the Mantis 80 make them capable of being used where standard bollards simply cannot be installed.

They require no pre-casting of the pit or additional rebar, ensuring installation is simple and efficient. Mantis Bollards can be installed in less than an hour by an experienced crew.
