The BCS allows for the connection of (2) 2x's to a 4x post or (3) 2x's to a 6x post. Double shear nailing between beam and post gives added strength. Do not install bolts into pilot holes. Install dome nails on beam; drive nails at an angle through the beam into the post below. 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). 18-gauge ZMAX galvanized coated steel.
