The wires are assembled together by welding at the cross over points. A series of iron rods (5) are added to the bottom rows of the horizontal wires. Fittings (7), which are provided with a series of regularly spaced hooks (8), are fitted over the iron rods, to act as anchorages. At the lower end of these fittings an attachment, in the form of a hook (12), is located and this is designed to be attached to the anchorage point (6), which is buried in the ground.</p> |
