The Heavy Duty Three-Way Pergola Corner Bracket is designed for professional builders and DIY enthusiasts looking to construct robust pergolas, gazebos, or custom timber frame structures. The primary benefit of this bracket is its ability to provide rock-solid, stable connections between 150mm wooden posts and beams, ensuring long-term structural integrity. While it offers superior strength and weather resistance through its powder-coated steel construction, users must ensure their timber dimensions are precisely cut to 150mm to fit the bracket sleeves properly.

No, this product does not include mounting fasteners. You should use exterior-grade lag screws or carriage bolts appropriate for your specific timber thickness.
These brackets are designed for 150mm timber. If you use smaller timber, there will be a gap that may compromise structural stability.
While the powder coating is highly durable, coastal environments are very harsh. We recommend regular inspections and touch-ups if the finish is scratched.
For a standard four-post square pergola, you would typically need four three-way corner brackets for the top plate connections.
The bracket is very strong, but you must ensure your vertical posts are also anchored correctly into the ground or a concrete base to handle the lateral tension of a shade sail.
Lightly sand or plane the edges of the timber post until it slides securely into the bracket.
Clean the affected area with a wire brush and apply a matching black metal touch-up paint to seal the exposed steel.
Ensure that the timber is fully inserted into the sleeve and that all mounting fasteners are tightened firmly into the structural wood.
To install, slide the 150mm timber posts and beams into the bracket sleeves. It is recommended to pre-drill pilot holes through the bracket's designated mounting points before driving in your exterior-grade lag screws or bolts to prevent the timber from splitting.
Compatibility is strictly limited to 150mm x 150mm timber sections; ensure your lumber is planed to the correct dimensions for the best fit. For maintenance, periodically inspect the connections for any signs of timber shrinkage, which may necessitate tightening the fasteners. You can clean the brackets with mild soap and water to remove dirt or debris; avoid using abrasive chemicals that could scratch the protective black powder coating.
