Description
Height-adjustable post base 110×110 mm, M20 thread – height 330 mm, galvanised
The height-adjustable M20 post base with a base size of 110×110 mm and a height of 330 mm is a robust steel connector designed for anchoring timber and steel posts in concrete foundations. Made of galvanised steel, it provides durable corrosion protection even in demanding weather conditions.

The post base consists of a base plate with mounting holes and a threaded rod that allows smooth adjustment of the post seating height. This allows the installer to level the structure precisely without the need for additional shims or wedges.
The heavy-gauge base plate ensures adequate rigidity and load-bearing capacity of the connection. The post base is fixed to the foundation using anchor bolts passed through the holes in the plate, while the post sits on the upper part of the base and is fastened to it with screws or bolts through the side holes. Adjustment on the thread compensates for foundation unevenness and allows the post to be set precisely plumb — particularly important for repeat installations, e.g. carports, pergolas or support structures for photovoltaic systems.
