Description
Height-adjustable post base 80×80 mm, M20 thread – height 330 mm, galvanised
The height-adjustable M20 post base with a base size of 80×80 mm and a height of 330 mm is a durable structural connector designed for the stable mounting of timber and steel posts on concrete foundations. Made of galvanised steel, it provides lasting corrosion protection in outdoor conditions.

The post base consists of a square base plate with mounting holes and a threaded rod that allows smooth height adjustment of the post position. A hexagonal nut securely locks the selected position, while the holes in the base allow it to be firmly bolted to the foundation.
The adjustable post base is particularly useful where the foundation surface is not perfectly level or where precise levelling of the structure is required. The threaded rod ensures a high load-bearing capacity of the connection, and the galvanised surface protects the component against moisture and weather conditions. The post base is suitable both for building structures — pergolas, carports, fences — and for installations that use posts as load-bearing elements, e.g. when assembling support structures for ground-mounted photovoltaic panels.
Design features
- Durable thread providing high load capacity and precise height adjustment
- Thick base plate ensuring rigidity and a stable fixing
- Mounting holes in the base for secure anchoring to the foundation
- Galvanised coating protecting against corrosion in outdoor conditions
- Smooth adjustment allowing perfect levelling of the post
- Lock nut for firmly fixing the selected position
- Sold individually — order the exact number of pieces you need
Applications
- Pergolas, shelters and gazebos — mounting timber posts in garden structures
- Fences and gates — fixing load-bearing posts on foundation footings
- PV support structures — posts for ground-mounted photovoltaic panel mounting systems
- Carports and canopies — durable connection of posts to a concrete foundation
- Renovation and adaptation work — correcting the level of existing foundations thanks to threaded adjustment
The post base is sold individually, so you can order the exact number of pieces required by your project. Its compact size (small parcel) makes storage and transport to the building site easier. Thanks to the standard M20 thread, the component is fully compatible with commonly available nuts, washers and chemical anchors.
