Description
Height-adjustable post base 160×160 mm, M24 thread – height 250 mm, galvanised
Height-adjustable post base 160×160 mm with an M24 threaded rod, 250 mm high — a robust structural connector designed for seating timber and steel posts on concrete foundations. Made of galvanised steel, it provides years of corrosion resistance in outdoor conditions.

The post base consists of two steel plates joined by a threaded rod. The lower plate anchors it to the foundation, while the upper plate secures the post. Height adjustment with a nut allows the post to be levelled precisely, even on uneven concrete surfaces.
Both plates are made of thick steel sheet, which ensures the rigidity and stability of the entire connection. Mounting holes in the corners and a central through-hole allow secure anchoring on both the foundation side and the post side. The zinc coating protects all components — the plates, the rod and the nut — against moisture and changeable weather conditions, so the post base is suitable for outdoor installation without additional anti-corrosion protection.
Design features
- Smooth height adjustment — the nut on the threaded rod allows precise levelling of the post
- Hot-dip galvanising — durable corrosion protection for outdoor applications
- Rigid base plate — stable support that prevents deformation under load
- Large bearing surface — even distribution of forces onto the foundation and the post
- Mounting holes in the corners of both plates make anchoring with standard fasteners easier
- Central through-hole — simple installation of the threaded rod
- Nut included — a complete component, ready to install without buying additional accessories
Applications
- Shelters and pergolas — mounting load-bearing posts on foundation pads
- Fences — seating timber and steel posts on a concrete plinth
- Timber structures — gazebos, carports and patio canopies with adjustable post levelling
- Light steel structures — supporting profiles on strip foundations
- Photovoltaic structures — anchoring ground-mount substructure posts to pad foundations
The post base is sold as a complete set: two steel plates, an M24×250 mm threaded rod and a nut. The sales unit is 1 piece. Thanks to its universal design, the component can be used with both timber posts and steel profiles — simply choose suitable anchor bolts for the mounting holes in the plates.
