Two similar trellises made of black locust, but with quite different mounting methods! On the left, on the insulated wall of the house, M12 trellis brackets for rigid insulation (AS 12XX6) were initially used. At the three upper fixing points on this wall, there may have been softer material (polystyrene) beneath the render, or a ring anchor there was not to be ‘drilled into’. In any case, three M8 “Styro” trellis brackets (AS 08555) were fitted at these points. On the right, on the uninsulated outbuilding, M10 “Classic-L” trellis brackets (AS 10180) were used.
