Description
Height-adjustable post base 80×80 mm, M20 thread – height 500 mm, galvanised
The M20 adjustable post bracket with a 80×80 mm base and a height of 500 mm is a durable structural connector designed for fixing timber and steel posts. Made of galvanised steel, it provides long-lasting corrosion resistance even in demanding weather conditions.

The bracket consists of a threaded rod mounted on an articulated joint in a steel base plate. The joint allows the angle of the spindle relative to the base to be adjusted, enabling precise plumbing of the post even on uneven ground. The plate has mounting holes positioned at the corners and along the axes, giving flexibility when anchoring to the foundation.
The galvanised protective coating covers the threaded spindle as well as the base plate and the joint, creating a uniform anti-corrosion barrier over the entire surface of the bracket. As a result, the component remains fully functional for years of outdoor use — in carports, pergolas, canopies, fences or as supports for photovoltaic structures. The thread along the entire length of the spindle allows smooth height adjustment of the post using standard nuts, which significantly speeds up installation and eliminates the need to cut components to size on site.
