Caps & Bases
The industry standard column caps. Precision factory gang-punched holes speed installation
on this product line.
MATERIAL: CC3 1⁄4, CC44, CC4.62, CC6, ECC3 1⁄4, ECC4, ECC4.62, ECC6—7 gauge;
all others—3 gauge
FINISH: Simpson Strong-Tie® gray paint; may be ordered HDG; CCO, ECCO—uncoated
INSTALLATION: • Use all specified fasteners. See General Notes.
• Bolt holes shall be a minimum of 1⁄32" to a maximum of 1⁄16" larger than the
bolt diameter (per 12.4.1.2 CSA O86-14).
• Contact engineered wood manufacturer for connections that are not through
the wide face.
OPTIONS: • Straps may be rotated 90° where W1 ≥ W2 (see illustration).
• For special, custom, or rough cut lumber sizes, provide dimensions. An optional
W2 dimension may be specified with any column size given (note that the W2
dimension on straps rotated 90° is limited by the W1 dimension).
• CCO//≥ECCO—Column cap only (no straps) may be ordered for field-welding to pipe or
other columns. No resistances apply. CCO/ECCO dimensions are the same as CC/ECC.
• CCOB—Any two CCO’s may be specified for back-to-back welding to create a cross
beam connector. Use the tabulated resistances; the resistance is no greater than
that of the lesser element employed.
• ECCU—Order when uplift resistance is required for end column cap applications.
• See page 73 for CCC, CCT and ECCL options.

1.Post sides are assumed to lie in the same vertical
plane as the beam sides.
2.Factored resistances may not be increased for short-term load duration.
3.Factored resistances are determined using φFcp equal to: 812 psi (5.6 MPa) for D.Fir-L and
672 psi (4.64 MPa) for Spruce-Pine glulam sizes; 1092 psi (7.53 MPa) for SCL sizes; reduce where end grain bearing or buckling capacity of post governs.
4.Spliced conditions must be detailed by the Designer
to transfer tension loads between spliced members
by means other than the column cap.
5.SCL assumes SG = 0.50.
6.Beam depth must be greater than H1.
7.Contact Simpson Strong-Tie for uplift resistances.
