Rapid

Rapid is an easy to handle spacer that is used during lower edge reinforcement. Advantages of the Rapid spacer include that it can cope with heavy loads and that it can be walked on when the mesh is in place.
Rapid provides good contact with the concrete and can be used with both reinforcement mesh or loose rebars. It couldn’t be any simpler – place Rapid spacers in the mould and then add the reinforcement!
However, note that Rapid should not be laid in a row one after another.
