A support in combination with an internally threaded ferrule (8) to be cast into a concrete product such as a panel, the support being engageable with a casting bed and comprising a ferrule support surface (4) for supporting the base of the ferrule (8) above the casting bed. The ferrule (8) has within its base part a transverse passage for a cross bar (12) for co-operation with reinforcement, the support further comprising clips (10) engageable with the cross bar to anchor the cross bar (12). The configuration of the clips (10) in relation to the ferrule support surface (4) of the support, the ferrule (8) and its cross bar (12) is such that when the cross bar (12) is engaged with the clips (10), the cross bar (12) applies to the ferrule (8) a downward force to force the base of the ferrule (8) into tight engagement with the support so as to engender factional locking between the ferrule (8) and its cross bar (12) sufficient to prevent slippage of the ferrule (8) relative to the cross bar (12). |
