Description

Product Overview

The Pirosim 4×4 Post Base is engineered to deliver reliable, long‑term support for a variety of outdoor construction projects. Constructed from solid steel with a wall thickness of 0.08 inches (2 mm), each base is powder‑coated to resist rust, UV exposure, and the harsh elements commonly encountered on decks, porches, and fences. The internal cavity measures 3.7 × 3.7 inches, perfectly sized for standard 4×4 wooden posts, ensuring a snug fit that prevents wobble and movement over time. The package includes ten individual bases, each measuring 6 × 6 × 2.5 inches, providing ample surface area for load distribution and stability.

The included expansion plugs and stainless steel self‑tapping screws (40 × 3‑1/8″ and 80 × 1‑1/4″) are specifically selected to match the base’s design, allowing for quick, tool‑free assembly in both DIY and professional settings.
