Rota Slot and Rota Block Barriers

The Rota Slot, Rota Block Mini, and Rota Block Large are water-filled ballast blocks designed to provide stability and safety for temporary fencing and hoarding.

Used widely on construction sites, street works, highways, and events, they prevent panels from toppling in high winds and improve overall site safety.

Each model varies in size and ballast weight, from the compact Mini for lighter fencing and pedestrian barriers, through to the Large for hoarding and higher wind resistance.

Together, the range provides secure, adaptable solutions that are easy to install, handle, and remove.
