LCB/CB Column Bases

Material: See table.

Finish: LCB, CB44, CB46, CB66 - 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" for CB, 2" for LCB.
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).

Options:

LCB and CB are available in rough size. Other sizes available for CB specify W1 and W2 dimensions. Consult Simpson for bolt sizes and allowable loads.
See Ornamental Notched CB.

Uplift loads have been increased 60% for wind or earthquake loading, with no further increase allowed; reduce
where other loads govern.
PSL is parallel strand lumber.
LCB products may be installed with either bolts OR nails (not both) to achieve table loads.
Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. Values in the tables reflect installation into the wide face. See technical bulletin T-SCLCOLUMN for values on the narrow face (edge). LCB bases installed with nails must be installed into the wide face.
