<p>A magnetic holding device (20) is provided comprising an elongate housing (22) containing a plurality of magnets (30) located at longitudinally spaced apart locations (28) of the housing (22). The device (20) thus has magnetic surfaces (31) for holding a sheet material (14) to a magnetically receptive surface of a steel frame member (16, 19) of a wall or roof framework for a building before the sheet material (14) is permanently secured to the frame member (16, 19). The elongate housing (22) also includes at least one adjustable retaining member (40) having a lip (44) for engagement with a side surface of the frame member (16, 19) to help prevent the holding device (20) and sheet material (14) from slipping relative to the frame member (16, 19), e.g. in windy conditions.</p> |
