LADECH 4x4 Post Bases – Heavy-Duty Internal Bracket Black (4 pcs) for Deck, Fence & Handrail

Rugged, purpose-built for outdoor wood posts

Engineered to fit standard 4x4 wood posts (actual 3.5" x 3.5"), the LADECH 4x4 Post Bases provide a solid foundation for deck columns, fence posts, porch railings, and related structures.
