A screed floor outlet box includes a base assembly 5 that includes a base frame 9 for attaching to a floor substrate over which a screed is to be laid, and a lid frame assembly (7, Fig 2) for fastening to the base assembly 5. The base frame 9 is formed from metal sheet bent approximately into the shape of a cuboid and comprising a bottom face (11, Fig 3a), side faces (13, Fig 3a) and an open top over which the lid frame assembly (7, Fig 2) is to be received. The base frame is formed from a single metal sheet. Preferably openings (14, Fig 3a) are provided in one or more side faces of the base frame. The lid frame assembly may be fastened to the base using a ratchet mechanism, which allows the vertical separation of the lid frame assembly from the base frame to be adjusted. Preferably, the base assembly further includes a tray (19, Fig 3a) mounted in the base frame and vertically spaced from the bottom of the base frame. |
