Drive-In Heavy Duty Post Anchor Ground Spike Support Bracket for 4" / 100mm Wood
Fix your timber posts securely into the ground with this Drive-In Heavy Duty Post Anchor Ground Spike Support Bracket. Designed for 4-inch (100mm) square timber, this bracket offers fast, stable installation without needing concrete or digging large holes.
The long cross-staked spike drives deep into firm ground or can be concreted in for extra stability. The unique cross shape gives superior hold in the soil, helping resist lateral movement and uplift. Once in place, the post slots into the top bracket and is fixed using the ten surrounding screw holes for a firm, level fit.
