Fence post extenders are designed to raise the height of existing fence posts by one metre without the need for full replacement. They provide a quick and practical solution for improving privacy, security, or adapting fencing to new requirements.
These fixings are widely used in fencing and landscaping projects where increasing height is more efficient than replacing posts.
What are fence post extenders?
Fence post extenders are metal brackets that fit over existing timber fence posts. They allow an additional section to be secured on top, extending the overall height.
They are commonly used when upgrading fences or making adjustments to existing structures.
Can post extenders be used with concrete posts?
Post extenders are typically designed for timber fence posts. They fit over the existing post and clamp securely in place.
