Protect Your Fence and Enhance Your Boundary
Outback Sleepers' Under Fence Plinths (UFPs) are designed to improve the durability, appearance, and functionality of your fence. Installed beneath fence panels, UFPs prevent panels from sitting in soil and corroding, extending fence life while providing a clean, finished look.
They also fill gaps beneath fences to improve privacy, contain garden soil, and deter pets from escaping — all without compromising the fence's structural integrity.
⚠️ Note: UFPs are not designed for retaining loads and must not be used in place of retaining wall sleepers.
