The adjustable fixture device for a frame (3) in an opening in a wall (1) comprises a frame casing (15) with an outer thread which engages in a bore in the frame. The frame casing has a pick-up formation internally both at the front and rear end for a hexagonal spanner. The frame casing externally is hexagonally shaped (16) at its ends for the block spanner, so that it can be readjusted without the fixture being loosened. The frame casing outer thread also has a less ground surface over the threads on two sides, so that it can be more easily drawn into the frame. Internally in the frame casing hexagonal channel (19) is a constriction (17) which defines a locating shoulder for fixture components in a wall. |
