Durable, weather-ready 4x4 post base for outdoor projects

Meet the YVHFWOY 4x4 post base brackets. Crafted from heavy-duty steel and finished with a black outdoor powder coating, these anchors are built to withstand the elements while maintaining a clean, modern look. The solid welds and robust construction give a tangible sense of stability, making outdoor frames feel secure from the first installation to years of use.

Smart specs for reliable fit

These bases are designed for standard 4x4 wooden posts. The inner opening measures 3.6 inches by 3.6 inches, while the outer footprint spans 5.9 inches long, 3.78 inches wide, and 5.5 inches tall. This combination helps you achieve precise alignment and a snug, steady hold for your posts.

  • Material: Q235B steel with a high-strength welded frame
  • Finish: black outdoor powder coating for weather resistance
  • Inner opening: 3.6" x 3.6"
  • Base footprint: 5.9" L x 3.78" W x 5.5" H
  • Bottom design: a raised square column keeps posts elevated from moisture

  • Decks and porches
  • Fences and railing systems

  • Mailbox posts and similar outdoor supports

Easy installation, complete kit

The package includes everything you need to get started: one wrench, 32 expansion bolts, 32 external-hex self-tapping screws, and 64 self-tapping screws, plus a straightforward manual to guide the setup. You can mount the bases to wood or concrete surfaces with confidence.
