4-Piece Square Post Support Brackets

A complete set of 4 black square post base brackets made from carbon steel, featuring welded square sockets and round flange bases with mounting holes. The coated surface enhances longevity and visual coherence across installations. These brackets are intended for securing square posts or rails directly to structural surfaces including timber decks, concrete foundations, or masonry walls. Their rigid design maintains alignment and minimises movement during and after installation — supporting stable, long-lasting setups for fencing, railings, and auxiliary structures.
