The SecureFix Direct Bolt Down Fence Post Holders are designed for DIYers and professional landscapers looking to install 4-inch (100mm) timber posts onto existing concrete bases or walls. By utilizing a robust bolt-down design, these holders eliminate the need for laborious digging or messy concrete mixing, effectively keeping wooden posts elevated to prevent rot and decay. While they offer a highly efficient installation process, users should note that the ground fixings required to mount the base plate to the concrete surface are not included in the set.

No, this set includes the bolts for the post-grip system, but ground fixings for mounting to the concrete must be purchased separately.
Yes, these are specifically designed for 4-inch (100mm) timber posts.
Yes, the brown finish is a durable coating designed to protect the steel from outdoor elements while blending with the wood.
No, these are bolt-down supports designed strictly for hard, level surfaces like concrete or solid stone.
This set contains 10 individual fence post supports.
Yes, by holding the post above the ground, it prevents moisture from wicking up into the wood, which is the primary cause of rot.
Check that the ground anchors are tightened fully into the concrete and ensure the twin-bolts on the side of the holder are firmly pressing against the timber.
Verify that your timber posts are exactly 100mm (4 inches). If the timber is pressure-treated and swollen, allow it to dry slightly or lightly sand the edges.
To install, ensure your concrete surface is clean and level. Position the support and mark the four 11mm bolt holes through the base plate. Use a masonry drill bit to create the pilot holes for your chosen ground anchors. Once the support is fixed to the ground, slide your 100mm timber post into the holder and tighten the two side bolts evenly to lock it in place. Periodically check the bolts after the first few weeks of use, as timber may shrink slightly over time, requiring a minor re-tightening to maintain a firm grip.
