Progola Post Base x4 (Suitable For: 4in / 100mm Post)

Build sturdy, professional outdoor structures with the Progola Post Base — a heavy-duty bracket designed to anchor 4″ (100mm) timber posts securely to any solid surface. Whether you’re constructing a pergola, fence, carport, or garden feature, this pack of 4 post bases provides the reliable foundation your project demands.

Simple, Rock-Solid Installation

The Progola Post Base fixes directly to concrete, brick, paving, or any solid surface using masonry bolts through the 10mm base holes. Once anchored, simply slot your 4″ timber post into the bracket and secure it through the staggered side holes (7.5mm) using wood screws. The carefully engineered hole pattern prevents internal screw collisions, ensuring a smooth, frustration-free install with a firm hold that keeps posts perfectly upright and aligned.

Engineered for the Outdoors

Each bracket is manufactured from a single piece of heavy-duty galvanised steel, delivering exceptional strength and long-term corrosion resistance in all weather conditions. The premium textured black powder coat finish adds a sleek, modern aesthetic while providing an extra protective layer against the elements — keeping your structure looking great for years to come.
