CCQ/ECCQ Column Caps

Column caps provide a high-capacity connection for column-beam combinations. This design uses Simpson Strong-Tie^® Strong-Drive^® SDS Heavy-Duty Connector screws to provide faster installation and provides a greater net section area of the column compared to bolts. The SDS screws provide for a lower profile compared to standard through bolts.

Material

• CCQ3, ECCQ3, CCQ4, CCQ4.62, ECCQ4, ECCQ4.62, CCQ6, ECCQ6 — 7 gauge; all others — 3 gauge

Finish

• Simpson Strong-Tie^® gray paint; available in HDG and stainless steel; CCOQ and ECCOQ — no coating

Installation

• Install 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. (Lag screws will not achieve the same load.) Install stainless-steel Strong-Drive screws with stainless-steel connectors.
• CCOQ and ECCOQ column caps only (no straps) may be ordered for field-welding to pipe or other columns. Dimensions are same as CCQ and ECCQ.
• For 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.)

Options

• For end conditions, specify ECCQ
• Straps may be rotated 90° where W₁ ≥ W₂ and for CCQ5-6

Load Tables

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

1. Uplift loads have been increased for wind or earthquake with no further increase allowed; reduce where other loads govern.
2. Down loads may not be increased for short-term loading and shall not exceed the post capacity. See Post Capacities for common post allowable loads.
3. Uplift loads do not apply to splice conditions.
4. Spliced conditions must be detailed by the Designer to transfer tension loads between spliced members by means other than the column cap.
5. Column sides are assumed to be aligned in the same vertical plane as the beam sides. CCQ4.62 models assume a minimum 3 1/2" wide post.
6. 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-C-SCLCLM for values on the narrow face (edge).
7. ECCQ uses 14 Strong-Drive® SDS Heavy-Duty Connector screws into the beam and 14 Strong-Drive SDS Heavy-Duty Connector screws into the post.
8. Beam depth must be a minimum 7".
9. For 5 1/4" engineered lumber, use 5 1/2" models.
10. CCOQ and ECCOQ welded to steel column will achieve maximum load listed as CCQ and ECCQ. Steel column width shall match beam width. Weld by Designer.
