The ABU is an adjustable post base which offers moisture protection and finished hardware appearance. Manufactured with ZMAX steel for enhanced corrosion resistance. These post bases feature a 1" stand-off height above concrete floors, code-required when supporting permanent structures that are exposed to the weather, or water splash, or in basements. They reduce the potential for decay at post and column ends. Post bases do not provide adequate resistance to prevent members from rotating about the base and are not recommended for non top-supported installations (such as fences or unbraced carports). Place the standoff base and then the post in the ABU and fasten using nails or Strong-Drive SD Connector screws or bolts.
