About this product Stable construction for secure support: The post bases are designed for 3.5' x 3.5' (approx. 88.9 x 88.9 mm) or 5.5' x 5.5' (approx. 139.7 x 139.7 mm) wooden posts. With their fully enclosed design, they ensure a firm, wobble-free stand and provide reliable stability for pergolas, railings, and support posts. Robust carbon steel with a 2 mm wall thickness: Made of durable carbon steel with a 0.08' (2 mm) wall thickness, the bases offer high dimensional stability and load-bearing capacity. The powder-coated or spray-coated finish effectively protects against corrosion and rust. Easy and quick installation: Pre-drilled screw holes allow for time-saving installation on wood or concrete surfaces. The post anchors can be efficiently secured using a standard drill and the included accessories. Complete accessory package included: Depending on the set size, the package includes M5x25 wood screws, M8x60 self-tapping screws, φ12x60 expansion bolts, washers, and matching open-end wrenches. The included mounting hardware facilitates immediate installation. Versatile applications: Suitable for concrete foundations and wooden decks. Ideal for pergolas, carports, patio roofs, fence posts, railing supports, or other load-bearing wooden structures in outdoor areas. Key differences: The 4' models (internal dimensions approx. 92 x 92 mm) are suitable for 3.5' wooden posts and are available in sets of 2, 4, 8, or 10. They differ primarily in set size and the number of accessories included. The 6' models (internal dimensions approx. 142 x 142 mm) are designed for 5.5' wooden posts and offer larger external and base dimensions for increased load-bearing capacity in heavier structures. Some versions also include base brackets and expansion bolts for particularly stable concrete mounting, while other sets are primarily designed for wood screw fixing. The total weight varies depending on the set size, ranging from approximately 2.15 kg (2-piece set) to 10.9 kg (10-piece set).
