QZER 4x4 Post Base (2 Pcs) – Heavy Duty Anti-Corrosive Post Anchor for Decks, Fences, Pergolas | 3.5x3.5 in, 13 Gauge Steel

Reliable anchor for outdoor posts

Meet the QZER 4x4 Post Base, a heavy-duty post anchor designed to secure square posts in decks, fences, pergolas, and other outdoor structures. The internal opening measures 3.5 by 3.5 inches, and the base can extend up to 5.5 inches high to accommodate varying ground levels and deck thicknesses, providing flexible mounting options without compromising stability.

Smart design blends strength with moisture management. A bottom partition keeps the wood elevated from direct ground contact, reducing rain exposure on the post and helping maintain a clean, neat appearance across seasons. This thoughtful feature complements the robust exterior and long-lasting construction, giving you a dependable foundation for outdoor projects.

Material and finish matter for outdoor use. The post base is crafted from thick 13-gauge steel, welded for rigidity, and finished with a black powder coating that resists rust and wear from sun, rain, and temperature shifts.

What you receive matters as well. The package includes a wrench, 8 expansion screws suitable for concrete or wooden floors, and 16 wood screws to secure the post. Optional mounting to concrete or wood floors provides installation flexibility to match your site conditions.

Key benefits at a glance

• Strong, durable construction: thick steel with welded joints anchors outdoor posts with confidence.
• Moisture-conscious design: bottom partition minimizes ground contact to help protect wood over time.
• Low maintenance finish: rust-resistant coating stands up to sun, rain, and seasonal changes.

Versatile applications illustrate how this base supports a range of outdoor projects. It’s well-suited for porch railings, pergolas, gazebos, fences, and mailbox posts. The compact footprint provides solid support without adding visual bulk, allowing your design to shine while maintaining stability.

• Decks and railings where a secure anchor is important
• Pergolas, gazebos, and outdoor structures needing solid footing
• Fences and mailbox posts that must stay aligned and upright

Note: While designed for strong, stable anchoring, real-world results depend on proper installation and site conditions.
