Simpson Strong Tie BCS2-3/6Z Dual Post Base 18GA Zmax

Product Description

The SIMPSON STRONG TIE BCS2-3/6Z is an 18-gauge steel dual post base designed to anchor wood posts to concrete or structural foundations in outdoor construction applications. It connects two 2x2 lumber members to a 4x4 post, or three 2x2 members to a 6x6 post, giving framers and structural contractors a single hardware solution for multiple post configurations. The ZMAX galvanized coating provides heavy-duty corrosion resistance suited to exterior and treated-lumber environments. Double shear nailing geometry increases load transfer at the connection point, and the fastener pattern is engineered to avoid end-grain nailing, which reduces post splitting during installation.

This dual post base is used in residential and light commercial outdoor structures including decks, pergolas, fences, and covered patios. It is intended for above-grade post-to-foundation connections where lateral and uplift resistance is required. Licensed carpenters, framers, and general contractors typically install this connector in new construction or deck replacement projects. The base accepts 16D common nails and is sold in a package of 10 units, making it practical for multi-post framing runs.

Key Features

• 18-gauge steel construction for structural rigidity at post base connections
• ZMAX galvanized coating for superior corrosion resistance in exterior and treated-lumber applications
• Accommodates two 2x2s to a 4x4 post or three 2x2s to a 6x6 post
• Double shear nailing design increases connection strength and load transfer
• Fastener pattern eliminates end-grain nailing, reducing risk of post splitting
• Installs with 16D common nails — no specialty fasteners required

Compatibility

Designed for use with 4x4 and 6x6 wood post assemblies using 2x2 lumber members. Suitable for outdoor structural framing applications where ZMAX-rated hardware is specified for contact with treated lumber.

Installation Notes

Installation is typically performed by licensed framers or general contractors in accordance with local building codes and the applicable provisions of the International Building Code. Ensure the base is fully seated and plumb before driving fasteners. Use only the fastener type and size specified for this connector — substituting fastener size or count affects rated load values. Do not install this connector in contact with incompatible chemical treatments without verifying corrosion compatibility with the coating rating.
