The Simpson Strong-Tie ECB66HDG ECB Hot-Dip Galvanized 2-in. Standoff Elevated Column Base for 6x6 is engineered by Simpson Strong-Tie to simplify the installation of waterproofing material on stacked balconies in multi-family buildings. Designed for use with hollow columns or solid-sawn posts, this elevated column base is the only post base available off the shelf that features a 2-in. standoff - providing enough room for moisture barrier material and a thin finish surface while still allowing for the 1-in. code-required standoff to prevent post decay. Its hot-dip galvanized finish delivers superior corrosion resistance, making it well suited for exterior and treated-wood applications.

Frequently Asked Questions

What makes the ECB66HDG different from other post bases on the market?

The ECB66HDG is the only post base available off the shelf that features a 2-in. standoff. This extra clearance provides enough room for moisture barrier material and a thin finish surface while still meeting the 1-in. code-required standoff needed to prevent post decay - a critical advantage for stacked balcony applications in multi-family buildings.

Can this column base be used with both hollow columns and solid-sawn posts?

Yes. The ECB66HDG is designed for use with both hollow columns and solid-sawn posts, offering broad versatility for a variety of construction scenarios.

What are the anchorage options for the ECB66HDG?

The ECB66HDG offers flexible anchorage options. It can be anchored to concrete using (1) 1/2-in. diameter Titen HD, Stainless-Steel Titen HD, or Titen Turbo anchor through the center hole, or fastened to wood using (4) 1/4-in. diameter Strong-Drive SDS Heavy-Duty Connector screws through the 4 corner holes. Additionally, (16) 0.148-in. x 1.5-in. nails are used into the column.

Why is hot-dip galvanization important for this column base?

Hot-dip galvanization (HDG) provides an extra layer of corrosion resistance, making the ECB66HDG especially suitable for exterior applications and use with treated wood, where exposure to moisture and chemicals can accelerate corrosion in standard hardware.
