The Simpson ECCLL444TC 4x4 Skewed Left End Column Cap is a precision-engineered structural connector from Simpson designed for end-of-beam column-to-beam connections where two beams meet in an "L" formation on top of a column. Built for a 4x beam and 4x post configuration with H1 and H2 stirrup heights of 6.5 inches, this skewed-left corner L-shape cap provides reliable load distribution from intersecting beams to a supporting column - making it a purpose-built solution for complex structural framing applications.

Key Features

• Skewed-Left Corner L-Shape Configuration - purpose-matched geometry ensures a precise, secure fit where two beams intersect at a column end, eliminating improvised workarounds in corner framing situations.
• 4x Beam and 4x Post Sizing - factory-matched to standard dimensional lumber, so the connector installs without modification and maintains tight tolerances at the connection point.
• 6.5-Inch H1 and H2 Stirrup Heights - the taller stirrup height accommodates beam depth requirements and keeps both intersecting beams securely captured within the cap for consistent load transfer.
• Certified Welds - engineered weld quality gives builders confidence in strength and load performance at critical connection points where structural integrity is non-negotiable.
• Steel Construction with Simpson Strong-Tie Gray Paint Finish - the steel build provides the rigidity required for structural column cap applications, while the factory-applied finish offers a layer of protection against surface corrosion during installation.
• Domestic Fabrication - built to consistent manufacturing standards, supporting quality expectations for structural connectors used in load-bearing framing applications.

Why This Product

• Engineered for a Specific, Difficult Connection - the skewed-left end column cap geometry solves a framing challenge that standard connectors cannot address, giving contractors a code-compatible solution for L-shape beam intersections at column tops without custom fabrication.
• Load Distribution You Can Specify with Confidence - the cap is designed to distribute loads from two intersecting beams to a single supporting column, with defined load parameters for the side beam and clear guidance on how combined loads must be calculated, making structural planning straightforward.
• Backed by a Trusted Structural Brand - Simpson is a well-recognized name in structural connectors, and this product reflects the same engineering standards applied across the broader column cap line, giving specifiers and inspectors a familiar reference point.
• Multiple Configuration Possibilities - while this listing covers the 4x4 setup, the ECCL cap platform supports a range of beam and post size combinations, making it a versatile starting point for projects with varying structural requirements.

Approved Applications

• End-of-beam column-to-beam connections where two beams meet in an "L" formation on top of a column
• Structural framing projects requiring a skewed-left corner end column cap configuration
• Applications requiring a 4x beam and 4x post connection with a tall 6.5-inch stirrup height
• Projects where load distribution from intersecting beams to a supporting column is required
• Structural connections where certified welds and NDS-compliant bolt spacing are necessary

Options

• Many combinations of beam and post sizes can be manufactured. Refer to worksheet Options for Multiple-Beam, Bolted Column Caps.?
• Contact us for Configurable Options and Special orders
  
• The download shall be determined from the allowable loads for the unmodified product (see ECC column caps). 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 cannot exceed the table load.
• Uplift loads do not apply for ECCL caps.
• 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 models ending in "44").
• 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 "No Straps" when ordering. Weld by designer. Full loads apply for the beam and the post cap.

Frequently Asked Questions

What post and beam sizes is the ECCLL444TC designed for?

The ECCLL444TC is designed for a 4x beam and 4x post configuration, with H1 and H2 heights of 6.5 inches.

What type of structural application is this column cap intended for?

This column cap is engineered for end-of-beam applications where two beams intersect in an "L" formation on top of a column. It helps distribute loads from the intersecting beams while providing structural support at the connection point.

What does the skewed-left orientation mean for installation?

The skewed-left orientation means the cap is configured to accommodate specific framing layouts where the L-formation is angled to the left. It is important to confirm your framing design requires a left-skewed direction before purchasing, as this cap is not interchangeable with a right-skewed version.

What features does the ECCLL444TC include to aid in installation and ensure structural compliance?

The ECCLL444TC includes diamond holes for convenient temporary fastening during installation, certified welds for strength and loading confidence at critical connection points, and bolt spacing that meets NDS code requirements for structural performance and compliance.
