Collection: Post Base

Post bases provide strong, durable connections between wood posts and concrete. Ideal for decks, patio covers, and other top-supported structures, these bases are made from hot-dip galvanized steel for long-lasting corrosion resistance. Non-standoff designs allow a tighter fit to concrete surfaces, while pre-punched holes simplify installation using nails or bolts.
