Product Features

• Heavy-Duty carbon Steel for Superior Durability Crafted from stainless steel plate and Φ5/8" threaded steel, this fence post anchor features a 0.2" thickened base plate with seamless welding for maximum strength and stability. The black powder-coated surface provides exceptional waterproof and rust-resistant performance, ensuring long-lasting durability in any outdoor environment.
• Moisture Barrier for Extended Wood Post Lifespan The U-shaped design effectively separates wooden posts from wet concrete, minimizing moisture exposure and significantly reducing the risk of wood decay. Ideal for fences, patio deck railings, yard posts, gazebos, pergolas, mailboxes, and more, this anchor enhances structural integrity and longevity for outdoor wood installations.

The anchor extends 8" above ground and embeds 8" into concrete, providing a solid foundation and superior load-bearing capacity to keep your wooden structures securely in place.
• Hassle-Free Installation in Three Simple Steps This complete installation kit includes all necessary screws and hardware for quick and secure assembly. Easy 3-step installation: ① Insert the anchor into wet concrete before it sets, ensuring it is level; ② Pre-drill holes in the wooden post and fasten with screws; ③ Insert the reinforcement rod through the post and tighten the nuts. No specialized tools required—just a drill, and you're set!
