K4 Bollard – PAS68

Who we have worked with...

Product Details

Embassies, military bases and sensitive sites are all areas that need to be kept secure, while also allowing easy access to authorised personnel.

Here at Expert Security UK, we provide a simple and cost-effective solution with our K4 bollards, which are designed to keep any premises protected from hostile vehicles.

Responsive security from the K4 bollard

Unlike traditional security measures, our K4 bollards can be lowered into the foundations of your premises to allow vehicle access. This is an effective way to allow emergency services quick and easy access to otherwise unauthorized areas.

A K4 bollard can be activated remotely whenever you need to provide access to your site. The bollard will be completely lowered in just 4 seconds and can be raised back up in under 7 seconds.

Always protected

By choosing a K4 bollard from Expert Security, you’re ensuring your premises receives round-the-clock protection.Our bollards have safeguards that ensure they remain engaged, even in the event of a blackout or power failure.

K4 bollards are also resilient against extreme weather conditions, as they can remain operational between -40°C and 60°C.

Bespoke to your premises

Each K4 bollard acts as an individual unit and is connected via its own hydraulics, so they can be positioned hower best suits your business needs. This makes them suitable for both open spaces and narrow pathways.

As our bollards can withstand up to 7.5 tonnes travelling at 50km/h, they will protect your property from even the most determined physical attack. This means that small entrances receive the same protection from a single K4 bollard as wider areas.

Installation made easy

Once you’ve chosen your K4 bollards, our team of professionals will begin by conducting a full survey to ensure your new product is right for your site. Our installation team will then arrive at your property at a date and time that is preferable to your day-to-day business, so not to cause disruptions.

Once your new bollards are up and running, we’ll perform a full handover to ensure you’re fully familiar with your product.
