Frequently asked questions

What fencing panels does the SlotBlock fit?

Each set is sized for a standard 3.5m-wide anti-climb temporary fencing panel, sold separately. The barriers are not designed for other panel widths.

Do the barriers need to be filled with water to work?

Yes. Each empty barrier weighs 14kg and is positioned by hand, then filled through the 75mm fill point - a full set weighs 160kg to 320kg, which gives the fencing its stability.

How windy can it get before the fencing is at risk?

The system is independently MIRA tested to withstand winds up to 57mph with fencing panels fitted, reducing the risk of a panel coming down on exposed or open sites.

What's included in one set?

One set is one white barrier and one red barrier, together sized to hold one standard 3.5m fencing panel upright.

What is the barrier made from?

100% recyclable high-density polyethylene (HDPE), chosen for durability and a low environmental footprint at end of life.

Can I get the barriers in a different colour?

The standard finish is red and white. Custom colours may be available on request - ask about trade-account options for bulk or framework orders.

How many sets fit on a pallet?

Ten sets per pallet, useful for planning site deliveries and storage space.
