This attachment is positioned and cast into the pre-cast unit at the factory. A Flexi Attachment (Art no. 1221) or Façade Bracket (Art no. 1223/1224 for Framed Barriers) is then fitted to the Precast Edge Attachment on site, to support the edge protection beyond the edge of the slab. This permits clear access for levelling off or completing other surface works whilst protected. The assembly will support the edge protection before the topping has been poured.
