The Gezu Impex Bolt Down Concrete Fence Pergola Post Bracket is an essential hardware solution for DIYers and contractors looking to secure 81 x 81 mm timber posts to concrete foundations. Designed for projects like pergolas, decks, and fencing up to 1.50 m in height, these brackets provide a high-strength, weather-resistant foundation through hot-dip galvanisation. While they offer excellent stability and moisture management, users should note that they are specifically engineered for timber installations and are not intended for structural load-bearing projects exceeding their 1.50 m height recommendation.

No, these are rated for posts up to 1.50 m. Exceeding this height compromises structural integrity and safety.
The package includes the brackets; masonry anchors and timber screws must be purchased separately based on your specific concrete type.
Yes, the hot-dip galvanised finish provides excellent protection against salt-air corrosion.
Yes, you can paint them using a metal primer followed by an exterior-grade paint if you wish to change the grey aesthetic.
No, this is a fixed-size bracket designed specifically for 81 x 81 mm posts.
No, these are strictly designed for concrete foundations and require a flat, hard surface for proper weight distribution.
Ensure the masonry anchors are fully tightened and that the timber post size matches the 81 x 81 mm specification precisely.
Ensure you are using high-quality hot-dip galvanized or stainless steel screws that are rated for outdoor, weather-exposed environments.
To install, ensure your concrete surface is level and fully cured. Position the bracket, mark the pre-drilled hole locations, and drill into the concrete using a masonry bit suitable for your chosen anchor bolts. Secure the bracket firmly to the concrete using heavy-duty masonry expansion bolts. Once the bracket is locked down, insert your 81 x 81 mm timber post into the sleeve and fasten it using galvanized timber screws or coach bolts through the side holes.
Compatibility is strictly limited to 81 x 81 mm square posts. While the galvanized coating is highly durable, you can maintain the aesthetic appearance and structural integrity by periodically checking that fasteners have not loosened due to thermal expansion and contraction. Avoid using harsh chemicals to clean the steel, as this may scratch the galvanized finish; a simple wash with mild soap and water is sufficient.
