Post caps for fence and gate posts
The cap closes off the top of the post tube. Without it, rainwater runs inside and stands above the concreted-in base. On a hot-dip galvanized post you see nothing of this for a long time; on a powder-coated post, corrosion works from the inside and causes the coating to flake off at the edge of the tube.
We supply plastic caps in packs of 10, because shipping a single cap costs more than the cap itself. Aluminum caps are available individually: flat, as a cube or with a ball. What always decides the choice is the tube cross-section of the post, not the shape of the old cap.
