Our Universal Concrete Intermediate Posts – also known as multi-holed posts – are a versatile 100mm x 100mm post with internal steel reinforcing bars. They suit feather edge close board fencing, where timber rails are bolted to the post, and can also be used as supports for retaining walls.
The posts are drilled with holes 75mm from the top and then at 150mm intervals, sized for 12mm bolts. They have a semi-dry finish, with a round top at one end and a weathered (slanted) top at the other, so you can choose which end goes up.

Choosing the right height

For a complete, long-lasting fence, pair with our fence panels, concrete gravel boards and post mix.
