The ECCLQ, CCCQ and CCTQ column caps provide high capacity, multiple beam to column connector options. The design uses Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws to provide faster installation and a lower profile compared to standard through bolts. Screws are configured to provide high uplift design values.

Material: 7 gauge.

Finish: Simpson Strong-Tie® gray paint, also available in HDG.


  • Install Simpson’s SDS 1/4″x2 1/2″ wood screws, which are provided, in all round holes. (Lag screws will not achieve the same load.)
  • No additional welding is allowed


  • Many combinations of beam and post sizes can be manufactured (refer to worksheet T-CCQLTC-WS).
  • Available in widths up to 8″ wide.
  • ECCLQ is available in left or right side beam orientations. Specify ECCLLQ or ECCLRQ.
  • Straps may be rotated where W1 > W2.
  • Column caps may be ordered without the column straps for field welding to a column. No loads apply.


  • The L dimension varies depending on the width of the side stirrup (W3 or W4). Contact Simpson Strong-Tie for exact dimensions.
  • Main beam stirrup height (H1) is 7″. Side beam stirrups (H2 or H3) can vary in height with the minimum height of 7″. Specify the side stirrup height from the top of the cap.
  • Example Order: 4x Main Beam, 6x Post, 4x Side Beam (oriented to the left) is ordered as an ECCLLQ464SDS.

Ordering Multiple-Beam Column Caps

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

  1. Choose Column Cap Style. Look at the configuration of the column caps to determine which style column cap 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 as 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.


  1. Uplift loads have been increased for wind or seismic; reduce where other loads govern. Downloads may not be increased.
  2. Allowable load is per seat. Side beams must be loaded symetrically for the CCCQ.
  3. The combined uplift loads applied to all beams in the connector must not exceed the total allowable uplift load listed in the table.
  4. The ECCLQ side beam may use a side beam uplift load up to 2350 lbs. The deflection of this load may exceed the standard 1/8″ deflection by an additional 1/8″.
  5. The combined download for all of the carried beams shall not exceed the allowable download for the unmodified product (CCQ load for CCCQ and CCTQ, or ECCQ load for ECCLQ). The download for each side beam shall not exceed the lesser of 35% of the allowable download or 9265 lbs. for the unmodified product.
  6. The download to each side beam shall not exceed the allowable load shown, nor 35% of the allowable load for the unmodified product, whichever is lower.
  7. Column width in the direction of the beam width must be the same as the main beam width (W1).
