Product Information
Full details
The Metpost Bolt Down Post Support is the ideal solution for DIY enthusiasts and professionals looking to mount timber fence posts onto existing concrete or solid surfaces. Its primary benefit is the raised base design, which keeps wood elevated to prevent rot, insect damage, and moisture absorption. While it provides excellent stability for 73-78mm posts, users should note that the surface must be level and structurally sound to ensure the bolt-down mechanism remains secure over time.

Extended Product Information
FAQs
Can I use this on soft soil or grass?
No, this product is designed exclusively for mounting onto solid surfaces like concrete or stone.
Does this support come with the bolts to fix it to the concrete?
No, the anchor bolts for the concrete base are typically sold separately to ensure you get the right type for your specific masonry.
What size timber post fits this support?
This support is designed to hold posts between 73mm and 78mm in width.
Can I paint the red oxide finish?
Yes, the red oxide coating acts as a primer, allowing you to paint over it with most exterior-grade metal paints.
How do I ensure the fence post is perfectly vertical?
Use a spirit level against the post while tightening the twin bolts to make small adjustments before the post is fully secured.
Troubleshooting
The post feels wobbly after installation
Ensure the twin bolts are tightened evenly on both sides and check that the base plate is flush against the concrete.
The post does not fit into the support
Verify the post measurement is between 73-78mm; if the timber is slightly oversized, you may need to plane the edges.
Rust appearing on the support
Lightly sand the affected area and apply a new layer of red oxide primer or exterior metal paint.
Pros and Cons
Pros
- Protects timber from ground moisture and rot
- Easier to install than traditional digging methods
- Can be easily painted to match fence colors
- Allows for replacement of damaged posts without concrete work
Cons
- Requires a solid, level concrete surface for mounting
- Visible hardware may not be ideal for all aesthetic preferences
- Not suitable for use on soft ground or soil
Setup, Compatibility & Care
Installation requires a masonry drill bit, a suitable drill, and four heavy-duty expansion bolts or coach screws depending on your concrete quality. The support is strictly compatible with 73-78mm timber posts. For maintenance, periodically check the twin bolts to ensure they remain tight, as timber can shrink or expand with seasonal weather changes. While the red oxide finish is durable, you may apply an outdoor-rated topcoat paint to prevent oxidation and to blend the support into your landscape. If you notice any signs of surface rust, clean the area and apply a touch-up of metal primer or matching exterior paint.
