The 100 x 100mm Fencemate Bolt Down Fence Post Holder Swift Clamp is a heavy-duty surface-mounted steel anchor designed to securely fasten 100mm x 100mm (4" x 4") timber posts to solid foundations such as concrete bases, brick walls, or timber decking. Sized specifically for larger structural posts, this bracket provides a dependable installation option for locations where ground spikes cannot be driven into the earth due to hard surfaces or paving.
 
Manufactured from robust structural steel and finished with a weather-resistant protective coating, this anchor is built to endure constant outdoor exposure and heavy wind loads. The wide baseplate incorporates pre-drilled holes for secure ground bolting, while the integrated swift-clamp mechanism utilizes a high-tension bolt system to clamp the timber post firmly in place without requiring complex drilling through the wood profile.
 
By raising the bottom of the timber post slightly above the solid surface, this holder prevents moisture from pooling underneath, effectively minimizing the risk of rot at the vulnerable end-grain. Whether you are erecting heavy boundary fencing, a pergola, or a secure gate post on a concrete patio, this trade-quality bolt-down support delivers exceptional structural rigidity and professional-grade performance.
