Zusammenfassung:A drain cover plate 18 or grating is mounted to a component 16. A boss 68a exposed to drainage flow spaces the cover plate or grating from the component to define inlet slots (88a-d, Fig.11). An upper surface portion of the cover plate or grating meets a surface of the component to provide a substantially step-free junction which is clogging resistant. A releasable fastener 20 may extend into the boss allowing the cover plate/grating to be secured to the component and/or the component to be secured to a drain body 12. Again this minimises division of the drainage flow and filament snagging. The component 16 may be a membrane clamp ring or a floor tile bezel/adaptor.
