About The Cladco Concrete Post Spacer Trim
The Cladco 3m concrete post spacer trim is designed to securely fit Cladco Signature composite fence panels into standard concrete posts. It reduces a typical 50mm groove down to 21mm, creating a snug, secure fit that ensures a stable and long-lasting installation.
If your current boundary features concrete posts and needs an upgrade, this metal spacer trim allows you to simply add Cladco Signature composite fence panels - no need to replace the posts.
Manufactured from rust-resistant, low-maintenance metal, the spacer is finished in grey to blend seamlessly with standard concrete posts.
Concrete fence post spacer trims are supplied in 3m lengths and can be cut to fit using tin snips if required.

For your Fencing project, square meterage is calculated by multiplying the total height of your fence by the total length of the boundary being fenced.
As each Composite Fencing Panel provides 0.72m coverage once installed, divide the square meterage by 0.72 to work out the total number of Panels required for your Fencing project.
Please note that our Composite Fencing Posts measure three metres in height, and, once installed, will allow for a maximum height of two metres, which equates to ten Panels.
