The Simpson Strong-Tie ECCLL444 is a heavy-duty L-Shape End Column Cap engineered for end-of-beam applications where two beams intersect in an "L" formation on top of a column. Built from 7-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, this skewed-left column cap is sized for nominal 4x main beams, a 4x post, and a 4x side beam, delivering reliable load distribution and structural support at the connection point. Bolt spacing meets NDS code requirements, and the cap installs with 5/8-in. diameter bolts for a secure, code-conscious build. For projects requiring the opposite orientation, order the ECCLR for the right-direction version.

Key Features

• Certified-weld assembly - every connection is built to verified strength standards, giving installers confidence in load-bearing performance without guesswork.
• NDS-compliant bolt spacing - engineered to meet National Design Specification code requirements, reducing the need for field modifications and supporting smooth inspection approval.
• Diamond holes for temporary fastening - allow the cap to be held in position during installation before final bolting, making alignment faster and easier for one- or two-person crews.
• 7-gauge steel construction - heavy-duty material thickness provides the rigidity and durability demanded by structural beam-and-post connections in demanding applications.
• Simpson Strong-Tie gray paint finish - factory-applied coating helps protect the steel during handling and installation in typical construction environments.
• Skewed-left L-shape geometry - purpose-built for end-of-beam column-to-beam intersections in the left orientation, eliminating the need for field fabrication or add-on brackets at the connection.
• Sized for 4x main beam, 4x post, and 4x side beam - exact member sizing means no guessing about fit; the cap is matched to specific plan details for a clean, accurate installation.

Why This Product

• Purpose-designed for L-shape beam intersections - unlike generic column hardware, this cap is specifically engineered for end-of-beam applications where two beams meet in an "L" formation on top of a column, providing a structurally appropriate solution without improvised workarounds.
• Certified welds plus code-compliant bolt spacing - the combination of factory-certified weld quality and NDS-aligned bolt layout means the connection meets recognized structural standards right out of the box, supporting both performance and inspection confidence.
• Reduces the need for additional brackets or braces - Simpson Strong-Tie column caps are designed to generally eliminate the need for supplemental hardware at the connection, keeping the build cleaner and the parts list shorter.
• Left-skewed geometry with a clear right-hand counterpart - the directional design is unambiguous, and a matching right-direction model is available, making it straightforward to specify the correct cap for either orientation on symmetrical or mixed-layout structures.
