Finish off your fence posts with a flourish, using these pyramid shaped caps, made from galvanized steel. With an internal width of 101mm (so perfect for 4 inch fence posts) these caps not only look good, but help prolong the life of your fencing as well, as they help stop water penetrating from the top - rain simply runs off the pyramid shape. The caps are 30mm in height and come complete with pre-drilled holes and screws for easy installation; two screws per cap will hold them in place.
