CRIZTA 4 Pcs 36-inch Heavy Duty 4x4 Fence Post Anchor Ground Spike

Effortless no dig installation for 4x4 posts

The CRIZTA 36-inch post anchors are designed to secure square wooden posts without digging holes or pouring concrete. They are sized to fit 3.5 x 3.5 inch posts, and you can drive the unit into the ground with a mallet or sledge using a scrap block of wood as a cushion. The result is a clean, straightforward setup that minimizes mess while delivering solid stake support for your project.

Durable, weather ready construction

Built from sturdy metal with a powder coated finish, these anchors resist rust and wear. The protective coating helps shield the timber from moisture exposure over time, contributing to stable posts along walkways, fences, and outdoor structures.
