The table below allows you to work out what your post centres will be. Example - If you have a 2400mm panel
and you are using Classic posts then you will have a 2530mm post centre to post centre measurement. If you
have a 2400mm panel and you are using Signature posts then you will have a 2630mm post centre to post centre
measurement.
* 3000mm high walls may not be suitable for all regions. Please consult Boundaryline prior to the design stage so we can
ascertain if additional materials are required example – Shortened free end spacing’s, deeper footings, core filling of posts
etc.
