Fence Support Spike 600mm x 100mm x 100mm (4" x 4")

Fence Support Spike measuring 600mm in length with a 100mm x 100mm (4" x 4") post socket. Designed to secure larger timber posts without the need for digging or concrete, it provides a durable and stable foundation for heavy-duty fencing and garden structures. Constructed from high-strength steel with a protective coating, it offers long-term resistance to corrosion and ground moisture. The four-finned anchor design provides a secure hold in firm soil, preventing movement under load. The 100mm square socket section grips the post securely, maintaining vertical alignment while keeping the timber base elevated above ground contact to reduce decay risk. At 600mm long, it is suited to firm or compacted soil where standard driving depth achieves reliable stability for 4-inch posts.
