I have some fence with concrete posts. The concrete posts are not the ones with the grooves in the sides so that fence panels can slide in between them. Instead they are solid with no grooves, but have holes drilled in them for cross beams of wood. Planks of wood have then been nailed to the cross beams to form the fence panels.
I have seen metal brackets to attach to concrete posts with grooves so that trellis can be attached on top, but these will not work with solid posts.
Does anyone know of a way to attach trellis to solid concrete posts?
