🏡 Tired of wobbly wood posts for your deck & pergola?
Our 4‑pack heavy‑duty 4x4 post‑base anchors are made of powder‑coated rust‑proof carbon‑steel. Inner 3.6"×3.6" cavity fits standard 3.5"×3.5" wood posts. Full‑wrap design reduces shaking, works for concrete or wood‑deck mounting with complete hardware included.
⚠️ Important: Only for actual 3.5"×3.5" wood posts. Light‑duty outdoor fixture use ONLY, NOT for main building structural load‑bearing posts. Drill tool not included.
Problems This Solves
❌ Loose, wobbly wood posts
Posts shift and shake without solid metal base anchor on deck or concrete.
❌ Outdoor metal brackets quickly rust
Uncoated steel corrode fast under yard rain & humidity, short service‑life.
❌ Missing matching installation hardware
Many post‑brackets sell only bare metal base; extra screws & anchors need separate purchase.
Key Benefits
📐 Precision‑Fit For Standard 4×4 Wood Post
Inner cavity 3.6"×3.6", perfectly fits real‑world 3.5"×3.5" lumber (market‑called 4×4 post). Full‑enclosed box‑style structure restricts side‑to‑side movement and minimizes post wobble. Not for oversized post or metal tubing; double‑check your lumber actual dimension before buying.
🛡️ Heavy‑Duty Rust‑Proof Carbon‑Steel
1.6‑mm thick carbon‑steel plate, resistant to bending & deformation. Matte black powder‑coated finish delivers corrosion and rust resistance for outdoor deck, porch, yard environment.
🔩 Dual‑Surface Mount & Complete Hardware Kit
Pre‑drilled mounting holes support installation on concrete (use included expansion plugs) OR wooden deck surfaces (use self‑tapping screws). Package supplies 18 M5 expansion plugs + 50 M5 self‑tapping screws plus manual. Drill power‑tool is NOT included.
Quick Setup Tips
Step 1
Confirm wood‑post actual dimension 3.5"×3.5".
Step 2
Drill holes; install base onto concrete / wood‑deck.
Step 3
Insert wood‑post; tighten all screws; re‑check tightness periodically.
Great For These Uses
Light‑duty fixture only; cannot be used for house main structural load‑bearing posts.
