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.

No, this product is designed exclusively for mounting onto solid surfaces like concrete or stone.
No, the anchor bolts for the concrete base are typically sold separately to ensure you get the right type for your specific masonry.
This support is designed to hold posts between 73mm and 78mm in width.
Yes, the red oxide coating acts as a primer, allowing you to paint over it with most exterior-grade metal paints.
Use a spirit level against the post while tightening the twin bolts to make small adjustments before the post is fully secured.
Ensure the twin bolts are tightened evenly on both sides and check that the base plate is flush against the concrete.
Verify the post measurement is between 73-78mm; if the timber is slightly oversized, you may need to plane the edges.
Lightly sand the affected area and apply a new layer of red oxide primer or exterior metal paint.
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.
