Drive-In Post Spike (Bolt Secure, Oxide Red) provides a fast, no-dig way to install timber fence and gate posts in firm ground. The heavy-duty steel spike is driven into the soil to form a secure foundation, while opposed clamping bolts grip the post above ground for a rigid, twist-resistant hold. The oxide red coating offers corrosion resistance and a clean, professional finish.
Key Features & Benefits
-
No-Dig Installation: Drive straight into firm ground—ideal where excavation would disturb paving, roots or services.
