Anchoring device for easily placing a grid

摘要

The fastening consists of a semi-cylindrical component with a threaded hole to act as a nut, having dimensions which enable it to be inserted sideways through the gap between two adjacent bars of the grating, using a tool in the form of an L-shaped rod with its tip engaging with a hole in one end face of the nut. Once the nut has been inserted it is turned through 90 degrees by pulling it upwards so that it interacts with the sloping undersides of the adjacent bars. With the tool holding it in position a bolt (18) can be inserted between the bars to fix an object such as a bracket (17) to the grating upper surface.
