ECB™ Elevated Column Base
Product Details
The ECB elevated column base for hollow columns or solid-sawn posts makes it easy to install waterproofing material on stacked balconies in multi-family buildings. It’s the only post base available off the shelf that features a 2” standoff, providing enough room for moisture barrier material and a thin finish surface while still allowing for the 1” code-required standoff to prevent post decay. There are two model sizes for 6x6 and 8x8 posts.
Key Features
- 2” elevated base accommodates moisture barrier and surface material while still providing 1” standoff
- Can be used with hollow columns or solid sawn posts
- Flexible anchorage options – 4 corner holes (screw down to wood) or 1 center hole (anchor to concrete)
Finish
- Simpson Strong-Tie gray paint; available in HDG
Installation
- Use all specified fasteners; see General Notes
- If using the single-anchor option (center hole), (2) 1/2" standard cut washers are required between the 1/2" anchor bolt or nut and the post base
- If using the four-anchor option (corner holes), install anchors into slotted holes at slight angle, as close to vertical as post base geometry will allow
- Concrete anchor options include Titen HD®, Stainless-Steel Titen HD, SET-3G™, or Titen Turbo™; wood anchor options include Strong-Drive® SDS Heavy-Duty Connector screw
- Post bases do not provide adequate resistance to prevent members from rotating about the base, and therefore are not recommended for non-top-supported installations (such as fences or unbraced carports)
