Description

Pergola Corner Brackets x4 (Suitable For: 4in / 100mm Post)

Create clean, professional pergola corners with the Progola 2-Way Corner Connector Bracket — a complete three-piece bracket system designed to join an upright post to a horizontal beam in a strong, flush L-shaped connection. Purpose-built for 4″ / 100mm timber, this pack of 4 complete bracket sets gives you everything needed to frame a full pergola, archway, pagoda, or gazebo.

Three-Piece Design for Maximum Strength

Each bracket set includes three components that work together for a fully enclosed, structurally sound corner joint. The outer corner piece locates and connects both timbers at the precise meeting point. The flat L faceplate secures to the opposite side, giving the joint a clean, encased appearance while doubling the fixing strength. The included internal L-bracket reinforces the inside of the joint, locking everything together for a connection that won’t shift, twist, or separate.

Precision-Engineered Installation

Each bracket set features 12 staggered screw holes (8mm diameter), carefully positioned to prevent internal screw collisions — even when combining with other Progola system brackets. Installation is straightforward: fix the corner bracket first, ensuring the upright post sits flush with the top of the bracket and the horizontal beam is pushed tight against both the post and bracket edge. Then secure the flat L faceplate on the opposing side and finish by screwing the internal L-bracket into the inner joint for a rock-solid hold.

Built for Outdoor Durability

Constructed from 2.5mm thick galvanised steel — heavier gauge than standard connectors — every bracket delivers serious load-bearing strength. The galvanised core provides permanent corrosion protection, even if the powder coat surface is scratched or damaged. The premium textured black finish gives a sleek, modern look that complements any outdoor timber structure.
