The Simpson Strong-Tie 4 inch Beam L-Shape End Column Cap ECCL4X is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections where two beams meet in an "L" formation on top of a column. Built to handle demanding load distribution requirements, this column cap is fabricated from steel with certified welds and designed to comply with NDS bolt-spacing code requirements - making it a reliable choice for structural applications where precision and code conformance are non-negotiable. Whether used with standard column straps or specified without straps for field welding to a steel column, this cap delivers robust performance at the intersection of post and beam framing.

Key Features

• Certified Welds - Gives builders and engineers confidence in the connection's strength and load capacity, reducing uncertainty in structural integrity.
• NDS-Compliant Bolt Spacing - Bolt spacing meets NDS code requirements, helping projects pass inspections and ensuring the connection performs as designed under load.
• L-Shape End Configuration - Accommodates two beams intersecting at a right angle on top of a column, making this cap the correct choice for corner and end-of-beam post-to-beam applications where a standard inline cap won't work.
• No-Strap Option Available - Can be ordered without column straps for field welding to a steel column, giving designers flexibility to adapt the connection to project-specific conditions (specify "No Straps" when ordering; weld by designer).
• Multiple Beam and Post Size Combinations - Many combinations of beam and post sizes can be manufactured, accommodating a wide range of structural framing layouts beyond the standard configuration.
• Side Beam Load Capability - The side beam can take a maximum of 40% of the download and shall not exceed 10,665 lb, providing clear, defined load parameters that simplify engineering calculations.
• Simpson Strong-Tie Gray Paint Finish - Provides a protective factory-applied coating suitable for covered structural applications, with HDG also available for environments requiring additional corrosion resistance.

Why This Product

• Purpose-Built for L-Shape End Connections - Unlike general-purpose column caps, this connector is specifically designed for the geometry of two beams intersecting in an "L" formation at the end of a beam run, ensuring a proper structural fit where other caps would require compromise.
• Code-Ready Construction - Certified welds and NDS bolt-spacing compliance mean the connection is built to meet code from the start, reducing rework and supporting smoother project approvals.
• Adaptable to a Wide Range of Projects - With many beam and post size combinations available and a no-strap field-weld option, this column cap can be configured to suit varied structural framing scenarios without sacrificing engineered performance.
• Clear Load Parameters for Confident Engineering - Defined side beam load limits and the requirement that the sum of side and main beam loads not exceed the table load give structural designers the specific values needed to engineer connections accurately and safely.

Specifications

• Manufacturer Part Number (MPN): ECCL4X
• Brand: Simpson Strong-Tie
• Beam Size: 4"
• Shape: L-Shape End Column Cap
• Material: 7 gauge or 3 gauge steel (depending on size)
• Finish: Simpson Strong-Tie Gray Paint (HDG also available - contact us for quote)

Approved Applications

• End-of-beam column-to-beam connections where two beams intersect in an "L" formation on top of a column
• Structural applications requiring load distribution from multiple beams to a supporting column
• Projects requiring column caps without column straps for field welding to a steel column (specify "No Straps" when ordering; weld by designer)
• Installations requiring compliance with NDS bolt-spacing code requirements

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 ECCL4X designed for?

The ECCL4X is specifically designed for end-of-beam applications where two beams meet in an "L" formation on top of a column. It provides a strong column-to-beam connection at these intersections, helping to distribute load from the beams and support the structural connection effectively.

What beam size is this column cap compatible with?

The ECCL4X is designed for use with 4" beams. It also accommodates many combinations of beam and post sizes, making it suitable for a wide range of project specifications.

What material and gauge of steel is used in the ECCL4X?

The ECCL4X is fabricated from steel in either 7 gauge or 3 gauge thickness, depending on the size. This heavy-duty construction supports demanding structural applications.

Does the ECCL4X meet any specific code requirements?

Yes, the ECCL4X features bolt spacing that meets NDS (National Design Specification) code requirements to ensure optimal performance and code compliance. It is also manufactured with certified welds, providing confidence in its strength and load-carrying capacity.
