The SecureFix Direct Bolt Down Fence Post Holders are ideal for homeowners and contractors looking to install 100mm timber fence posts on hard surfaces like concrete or stone without the need for manual excavation or pouring wet concrete. These holders provide a robust twin-bolt clamping system that ensures stability while keeping the wood elevated to prevent moisture-related rot and decay, though they are strictly intended for installation on existing hard surfaces and cannot be used in loose soil or dirt.

No, these are designed exclusively for solid surfaces like concrete or stone and will not provide stability in soft ground.
No, you will need to purchase anchor bolts suitable for your specific ground material, such as expansion bolts for concrete.
The base plate measures 173 x 173mm.
Yes, this set includes 2 units.
Yes, these are designed to fit 100mm posts, which is the metric equivalent of 4 inches.
The overall height of the support structure is 153mm.
Ensure that both side bolts are fully tightened. If the timber post has shrunk due to drying out, you may need to add a small shim or wood spacer to maintain a tight fit.
Check that the anchor bolts securing the base plate to the ground are fully tightened. Ensure the concrete beneath the base is not cracked or crumbling.
Clean the affected area with a wire brush to remove oxidation, then apply an exterior-grade anti-rust metal paint to seal the surface.
Installation requires a standard drill, masonry drill bits, and suitable anchor bolts (not included). First, place the base plate on the surface and mark the four bolt holes. Use a hammer drill to bore holes into the concrete to the depth required by your chosen fixings. Once the base is bolted securely, insert the 100mm timber post and tighten the side-mounted twin bolts until they bite firmly into the wood. Maintenance is minimal: periodically check the twin bolts to ensure they remain tight after high-wind events. Because the holders are painted, monitor for any chips or scratches that could expose the underlying metal to rust, and touch up with exterior-grade metal paint if necessary.
