PostSwap™ Raised Bolt-Down Post Support – 40mm Air Gap Galvanised Steel Post Base
The PostSwap™ Raised Base is a heavy-duty bolt-down timber post support designed to keep wooden posts 40 mm off the ground, helping reduce direct contact with standing water and moisture.
Its four-piece WrapLock design fits around the timber post and bolts together without welding. The post can later be removed and replaced by undoing the side bolts—ideal for installations where long-term serviceability matters.
Suitable for pergolas, gazebos, fencing, patios, decks, carports, canopies, privacy screens and other timber structures.
