The Simpson ECB66 2-in. Standoff Elevated Column Base from Simpson Strong-Tie is purpose-built to simplify waterproofing installation on stacked balconies in multi-family buildings. Designed for use with hollow columns or solid-sawn 6x6 posts, this column base is the only off-the-shelf post base that features a 2-in. standoff - providing enough room for moisture barrier material and a thin finish surface while still meeting the 1-in. code-required standoff to help prevent post decay.

Key Features

• 2-in. elevated standoff accommodates moisture barrier and finish surface material - gives installers the clearance needed for a complete waterproofing assembly without sacrificing the 1-in. code-required gap that protects posts from decay
• Compatible with hollow columns and solid-sawn posts - works across a wider range of balcony and post applications, reducing the need to source multiple base types for a single project
• Flexible anchorage options with 4 corner holes or 1 center hole - 4 corner holes allow screw-down attachment to wood substrates, while 1 center hole supports anchor-down installation into concrete, adapting to job-site conditions without additional hardware
• Cup 12 gauge with 7-gauge base and tube construction - heavier material at the base and tube provides structural durability where load transfer and moisture exposure demand it most
• Simpson Strong-Tie gray paint finish - provides a consistent, clean appearance suited to exposed column base installations while offering a baseline level of corrosion resistance

Why This Product

• The only off-the-shelf post base with a 2-in. standoff - contractors working on stacked balconies in multi-family construction do not have to fabricate a custom solution or wait for a special build; this elevated column base ships ready to install with the clearance built in
• Engineered for code compliance from the start - the 2-in. standoff is specifically designed so that after moisture barrier material and finish surface are in place, the required 1-in. code standoff is still maintained, reducing the risk of a failed inspection
• Two substrate anchorage methods in one connector - whether the structure calls for attachment to wood framing or a concrete deck, the ECB66 handles both with its dual anchorage hole configuration, making it a single-SKU solution across varying job-site conditions
• Broad post compatibility for multi-family and balcony applications - acceptance of both hollow columns and solid-sawn 6x6 posts means the same base can be used consistently throughout a project, simplifying procurement and installation planning

Frequently Asked Questions

What makes the ECB66 different from other post bases?

The ECB66 is the only post base available off the shelf that features a 2-in. standoff. This extra clearance accommodates both a moisture barrier material and a thin finish surface while still maintaining the 1-in. code-required standoff needed to help prevent post decay.

What type of posts is the ECB66 compatible with?

The ECB66 can be used with hollow columns or solid-sawn posts with a nominal size of 6x6.

What are the anchorage options for the ECB66?

The ECB66 offers flexible anchorage options: it can be fastened to wood using 4 corner holes with 1/4-in. diameter Strong-Drive SDS Heavy-Duty Connector screws, or anchored to concrete using 1 center hole with a 1/2-in. diameter Titen HD, Stainless-Steel Titen HD, or Titen Turbo anchor. Additionally, (16) 0.148-in. x 1.5-in. nails are used into the column.

What finish does the ECB66 have, and what gauge is it?

The ECB66 features a Simpson Strong-Tie gray paint finish. The cup is 12 gauge, while the base and tube are 7 gauge.
