Slot Block Barriers

Slot Block Barriers are the new revolutionary site safety barrier. It is the only water-filled barrier to hold a standard fencing panel to increase site safety, virtually eliminate potential trip hazards and give added stability to fence panels.

The Slot Block Barriers have been independently tested by MIRA testing. They will save time and money with the constant re-erection of site fencing and will give added visibility and corporate identity on ‘high profile’ sites. Contractors using the Slot Block Barriers will dramatically reduce their working footprint by an average of 500mm against a standard fence block.
