CCOB Column Cap Only, Back-to-Back
The CCOB is designed to provide a strong connection for the crossing of two beams. The design features two column caps without legs (CCOs) welded together back to back to create a cross-beam connector. This back-to-back column cap provides a high-capacity beam-to-beam connection.
- Uplift loads increased for earthquake or wind loading
- Bolt spacing that meets NDS code requirements to ensure optimal performance
- Diamond holes to provide temporary fastening
- CCOB3.62, CCOB4, CCOB44, CCOB5 1/4, CCOB5.50, CCOB6 — 7 gauge; all others — 3 gauge
- No coating
- Use all specified fasteners; see General Notes
- Weld by designer
- Bolt holes shall be a minimum of 1/32" to a maximum of 1/16" larger than the bolt diameter (per 2018 NDS, section 184.108.40.206); bolt holes should be drilled from one side all the way through the beam to maintain hole tolerances
- Contact engineered wood manufacturers for connections that are not through the wide face
- For special, custom or rough-cut lumber sizes, provide dimensions. An optional W2 dimension may be specified. (The W2 dimension on straps rotated 90° is limited by the W1 dimension.)

- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- Uplift loads do not apply to spliced conditions. Spliced conditions must be detailed by the designer to transfer tension loads between spliced members by means other than the post cap.
- Beam depth must be a minimum of 7".
- For 5 1/4" engineered lumber, use 5 1/2" models.
- Where top and bottom beam widths are different, use the lower allowable load.
