Our drains are 900mm long, 85mm Wide and 20mm deep.They allow for plenty of water to be drained away and not just flow over the top of them. They come with a 50mm outlet welded to the drain as per Australian Standards. This outlet is available on the end of the drain, at 50mm from the end or in the centre at no additional cost. Drains come with fall lines creased into drain to allow for smooth flow of water. End caps are fully welded.
