Overview

Meet the POSTYBAY 4x4 Fence Post Anchor Ground Spike, a heavy‑duty solution designed to stabilize outdoor posts with minimal effort. Crafted from solid carbon steel and finished with a black powder coating, this anchor adds a protective, weather‑ready edge to posts for decks, fences, porches, railings, or even mailboxes. The overall length is 16 inches, with a 4-inch upper segment and a 12-inch lower spike, and it accepts standard 4x4 wooden posts via an inner opening of 3.6 by 3.6 inches.

Solid, weather‑ready construction

The carbon steel body paired with a black powder coat resists rust and maintains a clean, professional look in outdoor settings. This combination supports long‑lasting stability while blending with wood tones and metalwork in yards and landscapes.

Dimensions you can rely on

The post anchor measures 16 inches in total length. The upper 4 inches are designed to be visible above ground, while the 12‑inch lower spike anchors into soil or concrete. The 3.6" x 3.6" inner diameter is sized for 4x4 posts, helping you achieve a snug fit that supports vertical alignment.

Easy installation

Install begins by driving the lower part of the spike into soil or concrete, then sliding the fence post into the upper sleeve. This straightforward approach is suitable for both DIY enthusiasts and professional craftsmen, enabling a quick, dependable setup.
