<p>The frame for a foot mat or foot grating is in the form of a flat trough (1, 2) made of plastics. The base (2) of this is fitted with outward extending anchoring protrusions on the underside. These protrusions (3) may be offset inwards by slightly more than the width of the trough vertical peripheral edge battens (1), and may incorporate at least one hole passing through them. There can be a central drainage pipe section (5), with the base sloping down towards this.</p> |
