Description
Product Overview
The QZER 4×4 Post Base is engineered as a heavy‑duty steel anchor that combines durability, corrosion resistance, and thoughtful design to meet the demanding needs of outdoor construction projects. Constructed from 13‑gauge solid steel, the base is powder‑coated with a black, rust‑proof finish that stands up to rain, UV exposure, and the abrasive forces of wind and soil. Its internal dimensions of 3.5″×3.5″ accommodate standard 4×4 wood posts, while the height of up to 5.5 inches provides ample support for a variety of applications, from deck railings to pergola columns. A distinctive anti‑corrosive partition at the bottom separates the post from direct ground contact, preventing water accumulation and wood rot over long periods of use. Each package includes eight expansion screws for concrete or wood floor installation, sixteen socket‑head wood screws for securing the post itself, and a sturdy wrench to simplify the assembly process.

FAQ
What post sizes are compatible with this base?
The base is designed for standard 4×4 wood posts with an internal opening of 3.5″×3.5″. It can also accommodate 6×6 posts when the larger size option is selected, provided the post dimensions fit within the base’s mounting holes.
Can this anchor be used on a wooden deck?
Yes. The included expansion screws are suitable for both concrete and wood surfaces. When installing on a wooden deck, pre‑drill pilot holes for the wood screws to ensure a tight, secure fit without splitting the deck boards.
Is the powder‑coat finish environmentally safe?
The powder‑coat used on the QZER post base is a low‑VOC, environmentally friendly coating that meets industry standards for safety and durability. It does not contain harmful heavy metals and is safe for residential applications.
How does the anti‑corrosive partition work?
The partition creates a physical barrier between the steel base and the ground, directing water away from the wood post. This design prevents moisture from pooling at the post’s base, reducing the likelihood of rot and extending the lifespan of both the post and the anchor.
