The Simpson Strong-Tie ECCL5 1/4X L-Shape End Column Cap is engineered for structural column-to-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. Sized for a 5 1/8" beam, this heavy-duty column cap transfers and distributes loads from the beams while providing critical support at the connection point. Certified welds and NDS-compliant bolt spacing make it a dependable choice for demanding structural work, and the cap can be configured to accommodate a wide range of beam and post size combinations per the project designer's specifications.

Key Features

• Certified Welds - Provides verifiable confidence in connection strength and load-carrying integrity, so structural connections meet professional standards without additional inspection uncertainty.
• NDS-Compliant Bolt Spacing - Meets National Design Specification code requirements, helping projects pass inspection and reducing the need for engineering workarounds at the connection point.
• L-Shape End Configuration - Purpose-built geometry for end-of-beam installations where two beams meet at a column in an "L" formation, eliminating the guesswork of adapting a general-purpose cap to a specialized layout.
• Heavy-Gauge Steel Construction - Available in 7 gauge or 3 gauge steel depending on size, delivering the structural rigidity required for high-load column-to-beam applications.
• Simpson Strong-Tie Gray Paint Finish - Provides a protective coating suited for structural environments, with HDG finish available for projects requiring enhanced corrosion resistance.
• Field Weld Compatibility - When ordered without column straps, the cap can be field welded directly to a steel column, giving designers and installers flexibility to meet site-specific structural requirements.
• Configurable for Multiple Beam and Post Combinations - Manufactured to accommodate many beam and post size pairings, reducing the need to source custom fabrications for varied project conditions.

Why This Product

• Engineered for a Specific Structural Challenge - The L-shape end column cap addresses the exact geometry of intersecting beams at a column end, providing a code-aware solution rather than a generic connector adapted to an application it was not designed for.
• Certified Welds Reduce Risk on the Job - Certified weld quality means structural connections carry documented assurance of strength, which matters for inspectors, engineers, and contractors who cannot afford uncertainty in load-path connections.
• Flexible Configuration Options Keep Projects Moving - The ability to specify different beam and post size combinations, stirrup heights, and strap options means this cap can be tailored to a wide range of structural layouts without requiring entirely custom fabrications.
• Trusted Simpson Strong-Tie Engineering Behind Every Connection - Designed and produced by Simpson Strong-Tie, a name widely specified by structural engineers and recognized by building officials, supporting smoother project approvals and long-term performance confidence.

Approved Applications

• Column-to-beam connections in end-of-beam structural applications
• Installations where two beams intersect in an "L" formation on top of a column
• Applications requiring load distribution from beams to column support points
• Structural connections requiring certified-weld column caps with NDS-compliant bolt spacing
• Field welding applications to a steel column when ordered without column straps (specify "No Straps" when ordering; weld by designer)

Options

• Many combinations of beam and post sizes can be manufactured. Refer to worksheet Options for Multiple-Beam, Bolted Column Caps.
• 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 type of application is the Simpson Strong-Tie ECCL5 1/4X designed for?

The ECCL5 1/4X is designed for end-of-beam applications where two beams intersect in an "L" formation on top of a column. It provides a strong column-to-beam connection at the point where beams meet, helping to transfer and distribute loads from the beams while supporting the connection.

What beam size is the ECCL5 1/4X compatible with?

The ECCL5 1/4X is designed for use with a 5-1/8" beam. It is part of Simpson Strong-Tie's ECCL product series, which can be manufactured in many combinations of beam and post sizes to meet designer specifications.

Does the ECCL5 1/4X meet any structural code requirements?

Yes, the ECCL5 1/4X features NDS code-compliant bolt spacing to ensure optimal structural performance, and it includes certified welds that provide confidence in its strength and load-carrying capacity.

Are there any features on the ECCL5 1/4X that assist with installation?

Yes, the ECCL5 1/4X includes diamond holes that provide convenient temporary fastening during installation, making it easier to position and secure the cap before completing the final connection.
