FAQs
Is the mounting hardware included?
No, the M10 screws or concrete anchors must be purchased separately based on the specific type of concrete or masonry surface you are using.
Can I use this for larger posts?
No, this support is specifically precision-engineered for 91 mm wooden posts.
Does the silver finish require painting?
The hot-galvanized finish is designed for durability and does not require painting, though it can be painted with suitable metal primers if desired for aesthetic reasons.
What is the thickness of the steel used?
The steel has a material thickness of 5 mm.
How does this prevent wood rot?
The design includes a base plate that elevates the bottom of the wooden post, preventing it from sitting directly on damp or wet concrete surfaces.
Troubleshooting
Post feels wobbly after installation
Ensure the M10 concrete anchors are fully tightened and the base plate is level on the concrete surface.
Difficulty inserting the wooden post into the sleeve
Verify that your post is exactly 91 mm. If the wood has swollen due to moisture, allow it to dry or lightly sand the edges.
Pros and Cons
Pros
- Heavy-duty 5 mm steel construction for maximum stability

- Designed to extend the lifespan of wooden posts by preventing decay
- Easy-to-use mounting system for quick DIY installation

- Requires a flat and level concrete surface for optimal performance
Setup, Compatibility & Care
To install, position the base plate on your concrete surface and mark the anchor locations through the pre-drilled holes. Use a masonry drill bit to create holes for your M10 concrete anchors. Tighten the anchors until the base plate is firmly seated against the concrete. Insert the wooden post into the sleeve and secure it using appropriate wood screws. Periodically inspect the connection points to ensure hardware remains tight. While the galvanized coating is highly resistant to weather, rinsing the base with fresh water during seasonal cleaning can remove abrasive debris or chemical runoff.
