Key Features
  • 【430 STAINLESS STEEL CONSTRUCTION】Unlike ordinary powder-coated steel brackets that are prone to fading, peeling, and rusting over time, Garvee post bases are crafted from genuine 430 stainless steel with a sleek black surface treatment. This material provides superior corrosion resistance and maintains its structural integrity in rain, snow, humidity, and coastal environments. Minimal maintenance required.
  • 【PERFECT FIT FOR 4X4 WOOD POSTS】Precision-engineered with a 3.6" x 3.6" inner size, these post brackets are designed to securely accommodate standard 4x4 lumber (actual wood dimensions 3.5" x 3.5"). Each bracket delivers a snug, wobble-free fit that keeps deck posts, fence posts, and pergola supports firmly in place for years of reliable performance.
  • 【COMPLETE KIT WITH ALL HARDWARE INCLUDED】Each set comes with post bases plus expansion pipes and self-tapping screws in one complete package — everything needed for a smooth installation. The multi-piece kit delivers solid per-unit value while saving you the hassle of sourcing hardware separately or making multiple purchases for larger projects.
  • 【TOOL-FRIENDLY EASY INSTALLATION】Pre-drilled mounting holes on both top (8 holes) and bottom (4 holes per bracket) allow for quick, hassle-free setup. Simply position the bracket on your concrete foundation or wood surface, secure with included hardware, insert your 4x4 post, and fasten. Perfect for DIY homeowners and professional contractors alike.
  • 【VERSATILE OUTDOOR USE】Designed for a wide range of residential and commercial applications — decks, pergolas, fences, porches, railings, handrails, gazebos, mailbox posts, garden trellises, and more. The clean black finish blends seamlessly with any outdoor aesthetic while providing the robust structural support your project demands.
