Abstract
A moulding accessory to form a void around a recessed lifting loop in a moulded concrete product such as a concrete cladding panel. The moulding accessory is formed from a body which is sized and shaped to fit with said lifting loop. The body is hollow, but sufficiently strong to form the void when concrete is poured. The body permits access to the lifting loop without needing to remove the body from the void. A method of forming a concrete product is also disclosed.
