ABSTRACT:
Surface drainage apparatus comprises a channel body defining a drainage channel with a cover defining apertures through which drainage can pass into the drainage channel. A fixing means is provided for attachment of the cover to the channel body and comprises a first fixing element for attachment to the channel body and a complementary second fixing element for attachment to the cover. The channel body defines at least one universal receiving aperture into which one of a plurality of differently constructed first fixing elements is capable of being located both before and after installation of said surface drainage apparatus. In this way both the production costs and the operating costs of the surface drainage apparatus can be reduced, especially when conversion is necessary.
