ECC/ECCU Column Caps
This page for Canadian customers only.

The industry standard column cap. Precision factory gang-punched holes speed installation on this product line. Strap sizes are specifically designed to meet Canadian code requirements.
Canadian Column Caps Discontinued in 2012
The unique Canadian versions of column caps are no longer necessary due to changes in the CSA Standard 086 – Engineered Design in Wood (2009). Please use the standard column caps.
See page 70 of the Canadian Catalog (C-CAN12) for factored resistance loads of standard CC Column Caps.
Material: ECC3 1/4C, ECC44C, ECC46C, ECC48C, ECC64C, ECC66C, ECC68C,
Finish: Simpson gray paint; may be ordered HDG, ECCO - no finish.
Installation:
- Use all specified fasteners.
- Bolt holes shall be a minimum of 1/32" to a maximum of 1/16" larger than the bolt diameter (per 10.4.1.2 CSA O86-01).
- 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).
- Column caps with W1, L, H1, and hole schedules different from the table may be special ordered. Provide a drawing to ensure accuracy. Provide a drawing to ensure accuracy.
ECCO - Column cap only (no straps) may be ordered for field-welding to pipe or other columns. No loads apply. ECCO dimensions are the same as ECC.
ECCU - Order for uplift applications.
ECCL - L Column Cap. 7 gauge stirrups may be welded to column cap sides. Factored uplift resistances do not apply to side stirrups. ECCL has no factored uplift resistance. Column cap only (no straps) may be ordered for field welding to pipe or other columns. No loads apply. Specify ECCOL and direction right or left.
The following criteria apply:
- The side stirrup maximum factored download cannot exceed 40% of the factored normal resistance in the table for the unmodified product, and cannot exceed 14,675 lbs (65.36 kN). The sum of the loads cannot exceed the tabulated resistance. The column width in the direction of the beam width must be the same as the beam width: W1.
- Specify the stirrup height from the top of the cap. The minimum H2/H3 for the stirrup is 6 1/2".
- The L dimension may vary depending on W3 or W4.
Ordering examples: An ECCLR66C with W3 =
3 5/8" , H2 =7 1/2" is an ECC66C end column cap with a 4x beam on the right side (specify L instead of R for left side stirrup) and stirrup seat 1" below the cap seat.

- Post sides are assumed to lie in the same vertical plane as the beam sides.
- Factored resistances may not be increased for short-term load duration.
- 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 bearing or buckling capacity of post governs.
- Factored uplift resistances have been increased 15% for earthquake or wind loading; reduce for other load durations in accordance with the code.
- ECC downloads assume a post of W1 x W2.
- Specifier to design beam for factored uplift resistance based on effective shear depth as per 10.2.1.4 CSA O86-01
- SCL assumes SG = 0.50
- Beam depth must be greater than H1.
