Unlike a bolt-down bracket fixed to an already-cured footing, this is a \"concrete-in\" (recessed) support: a round steel anchor rod – 16mm diameter on the 70mm size, 18mm on the 90mm size – is cast directly into wet concrete when the footing is poured, so the fixing becomes embedded and immovable as the concrete cures around it.\u003c\/p\u003e\n\u003cp\u003eOnce the concrete has cured, the concealed upper section sits proud of the surface and holds the timber post, while the fixing itself stays out of sight below – giving a noticeably cleaner finish than a traditional exposed bracket where the base plate and bolts remain visible around the foot of the post. This concealed profile suits anywhere appearance matters as much as strength, such as pergolas, gazebos and garden structures in view from the house or a patio. It isn't a lightweight decorative fitting: the upper plate is a full 8mm thick and hot-dip galvanised for long-term outdoor corrosion resistance, built to carry genuine structural load, and is CE marked under a European Technical Assessment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHot-dip galvanised finish throughout -
