Simpson Strong-Tie CB Column Bases
CB column bases help connect posts to concrete for a broad range of members. CB bases accommodate glulam and solid sawn members ranging from 4″x4″ up to 12″x12″.
Material:
Strap: CB4x, CB5x, CB6x — 7 gauge; CB7x and larger — 3 gauge
Base: CB4x through CB9x — 7 gauge; CB10x — 3 gauge
Finish:
CB44, CB46, CB66, CB68 — galvanized; all other CB — Simpson Strong-Tie® gray paint or HDG.
Installation:
- Use all specified fasteners; see General Notes
- For full loads, minimum side cover required is 3″
- Install all models with bottom of base plate flush with concrete
- 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)
