The flush fit bolt down post support in oxide red is designed to anchor 100mm x 100mm timber posts directly onto concrete, paving or masonry surfaces. The flush base plate sits level with the fixing surface, providing a neat, low-profile finish suited to decking frames, fencing and other outdoor timber structures.

Specifications

What it's used for

• Fixing deck posts to existing concrete or paved bases where a flush, tidy finish is required
• Installing fence posts to concrete footpaths, driveways or yard surfaces without digging
• Anchoring pergola or garden structure uprights to hard standing areas
• Replacing rotted in-ground posts by bolting directly to an existing concrete pad

Fitting and handling

Position the base plate on a clean, level surface and mark the bolt hole positions before drilling; use anchor bolts rated for outdoor use in the appropriate size for your substrate. Ensure the socket is plumb before tightening fixings fully, as adjustment is not possible once anchor bolts are set. Store brackets in dry conditions prior to installation to avoid any surface contamination that could affect adhesion if you plan to apply additional sealant around the base.

FAQ

Will this post support work with pressure-treated 100mm x 100mm fence posts?

Yes. The socket is sized for standard 100mm x 100mm sawn or treated timber posts. Pressure-treated posts may have a slightly varied finished size depending on the supplier, so check the actual cross-section before ordering if your posts are regularised or planed.

What anchor bolts do I need to fix this to concrete?

Resin anchors or mechanical expansion bolts in M10 or M12 are commonly used, depending on the load and the condition of the concrete. Always follow the bolt manufacturer's guidance on minimum embedment depth and edge distances for outdoor structural applications.

Is the oxide red coating sufficient for long-term outdoor use?

The oxide red finish provides an additional layer of corrosion resistance over the galvanised steel base, making it suitable for typical outdoor conditions in the UK. In coastal or particularly exposed environments, inspect fixings periodically and consider applying a zinc-rich cold galvanising spray to any cut or abraded edges.
