Slot-In Concrete-In Anti-Pullout Post Base Bracket for 4" / 100mm Wood
Secure your 4-inch (100mm) timber posts with this heavy-duty Slot-In Concrete-In Post Base Bracket. Ideal for fencing, pergolas, garden structures and decking frames, it provides a strong, reliable base without the need for above-ground fixings or deep post holes.
