Product Information

The Defender is a cost effective high security bollard available in a manually retractable or automatic version.

This product has been tested in accordance with the American DOS certification and achieved a K4 certified pass. Available as standard with a high visibility yellow paint finish or the option of a stainless steel sleeve if preferred. Perfect for any urban environment and very easily serviced and maintained.

The Defender K4 impact tested bollard provides excellent pedestrian and vehicle permeability and is available in a variety of operating sets and arrays. The Defender bollard is an economical and effective way of protecting your vehicle access points.

Available with an automatic, fixed or manually retractable operation, this range offers low operating and maintenance costs and is ideal for securing wide entrances where installing larger systems could become price prohibitive.

The manually retractable product variant is operated via a hand-held battery drill. This removes the need for any power infrastructure to be installed to raise and lower the product and is perfect for remote sites which only require a few operations each day. The product can also be operated using a hand-held turning handle as an alternative to the battery operated drill. This method of operation also offers significant health and safety benefits in comparison to normal manually retractable security products. The operator is not subjected to a lifting weight when raising or lowering the bollard.

The manually retractable product can be retro-upgraded to be hydraulically operated if required providing hydraulic ducts are installed when the product is first instated.

All steel parts are standard hot dipped galvanised for corrosion protection.

K4 impact test certified after successfully arresting a 6.8 ton (6,800 kg) vehicle travelling at 48km/h (30mph).
