Simpson Strong-Tie ABW66RZ 150mm x 150mm Standoff Post Base Pre-Galvanised

Adjustable Retrofit Post Base for Moisture Protection and Stability

The Simpson Strong-Tie ABW66RZ is a retrofit adjustable standoff post base, designed to provide a durable and economical solution for securing large timber posts while minimising exposure to moisture. With a 25mm stand-off height, this base helps prevent wood rot by elevating the post above ground level, ideal for decking, fencing, pergolas, and other outdoor timber structures.

Manufactured from pre-galvanised steel, the ABW66RZ offers reliable corrosion resistance and strength in non-structural or lightly loaded applications. Lateral restraint is required when installing this product to ensure full stability.
