ECCL/CCC/CCT Column Caps


Column-to-beam connections often have multiple beams framing on top of a column. L, T and cross-column caps provide design solutions for this application. Many combinations of beam and post sizes can be manufactured with the following criteria applied:

  • The download capacity shall be determined from the capacity for the unmodified product (See CC/ECC/ECCU Column Caps for more information). The side beam can take a maximum of 40% of the download and shall not exceed 10,665 lb. The sum of the loads for the side beam(s) and main beam can not exceed the table load.
  • Uplift loads do not apply for ECCL caps. For CCC and CCT, uplift loads from table apply for main beam only.
  • The column width in the direction of the main beam width must be the same as the main beam width (W1).
  • Specify the stirrup height from the top of the cap. The minimum side stirrup heights (H2 or H3) is 6 1/2" (3 1/2" for 44s).
  • The L dimension may vary depending on the width of the side stirrup (W3 or W4).
  • Column caps may be ordered without the column straps for field welding to a steel column. Specify CCOC/CCOT/ECCOL. Weld by Designer.


  • 7 gauge


  • Simpson Strong-Tie® gray paint; also available in HDG


  • Use all specified fasteners; see General Notes
  • Bolt holes shall be a minimum of 1/32" to a maximum of 1/16" larger than bolt diameter (per NDS 2015


  • Many combinations of beam and post sizes can be manufactured. Refer to worksheet Options for Multiple-Beam Column Caps (T-C-CCQLTC).

Ordering Information

Ordering Examples:

  • A CCC66 with W3 = 5 1/2", H2 and H3 = 6 1/2" is a CC66 column cap with 5 1/2" beams on each side with all beam seats flush.
  • An ECCLR66 with W3 = 3 5/8", H2 = 7 1/2" is an ECC66 end column cap with a 4x beam on the right side (specify direction left [which is shown] or right for stirrup) and stirrup seat 1" below the cap seat.

Ordering Multiple-Beam Column Caps:

Ordering bolted column caps incorporates several key steps important to ensure the highest-capacity solution for your project. Here are some common steps to begin that process. For more information, refer to worksheet T-C-CCLTC-WS for bolted connections and T-C-CCQLTC for Quick Install connections. See page 2 of worksheets for model numbers of common post and beam width combinations.

  1. Choose Column Cap Style. Look at the configuration of the column caps to determine which style you require. If you don’t know which style column cap is required, refer to your plans to determine the correct configuration.
  2. Determine Column Cap Dimensions. Fill in the dimensions of the column cap on the worksheet. If you don’t know the dimensions of the column cap, go directly to the “Post and Beam Dimensions” section.
  3. Provide Beam and Post Dimensions. The “Post and Beam Dimensions” section of this worksheet is required. Fill in all applicable dimensions in actual inches, not nominal dimensions.
  4. Determine Beam Orientation. Refer to your plans or check the configuration of the column cap you selected in order to determine the orientation of the beam. Check the box for the beam orientation that best describes your beam configuration: Beam B flush at bottom of Beam A; Beam B flush at both the top and bottom of Beam A; or Beam B flush at top of Beam A.
  5. Check the box for the required style and strap orientation.
  6. Select Finish. Standard finish is Simpson Strong-Tie® gray paint, available in HDG (specify HDG).
  7. Place Order. Contact Simpson Strong-Tie for ordering information.
