A gauge (10; 110) for levelling a tread (42; 142) of a step (40; 140) made from concrete, the gauge (10; 110) comprising a surface (14; 114) which is, in use, adapted to be drawn across the tread (42; 142) to level same. The gauge (10; 110) also comprises a guide (16; 116) which is shaped and dimensioned to engage an edge (48; 148) of an adjacent step (40; 140) while the surface (14; 114) is being drawn across the tread (42; 142), in order to maintain the correct position of the surface (14; 114) relative to the tread (42; 142) during use. The position of the guide (16; 116) relative to the surface (14; 114) is adjustable in order to allow the gauge (10; 110) to be used with steps of various dimensions. |
