The Simpson Strong-Tie ECCL3 1/4X 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. Sized for a 3-1/8 in. beam width, this column cap is built to distribute load from the beams and deliver critical structural support at the connection point. Constructed from 7 gauge or 3 gauge steel with certified welds and NDS code-compliant bolt spacing, it is a precision-engineered solution for demanding structural column-to-beam connections.

Key Features

• L-Shape End Configuration - Purpose-built geometry supports end-of-beam intersections where two beams meet at a column, giving designers a reliable hardware solution for this specific structural condition.
• Certified Welds - Weld certification provides confidence in strength and load performance at every connection point, reducing risk in critical structural assemblies.
• NDS Code-Compliant Bolt Spacing - Bolt spacing meets NDS code requirements, helping projects pass inspection and ensuring the connection performs as structurally intended.
• Heavy-Gauge Steel Construction - Made from 7 gauge or 3 gauge steel depending on size, delivering the material strength needed for load-bearing column cap applications.
• Simpson Strong-Tie Gray Paint Finish - Factory-applied finish provides a consistent, professional appearance right out of the box, with HDG available for projects requiring enhanced corrosion resistance.
• Field Welding Compatible - Available without column straps for direct attachment to a steel column, expanding the range of jobsite conditions and structural configurations this cap can serve.

Why This Product

• Engineered for a Specific Structural Challenge - End-of-beam column connections in an "L" formation require a cap designed precisely for that geometry. This product addresses that exact condition rather than relying on a general-purpose workaround.
• Code Compliance Built In - Certified welds and NDS-compliant bolt spacing mean the structural connection meets recognized standards from the start, reducing the burden on contractors and engineers during inspection.
• Flexible Configuration Options - Many combinations of beam and post sizes can be manufactured, and the product can be specified without column straps for field welding to a steel column, making it adaptable to a wide range of project requirements.
• Load Distribution Engineered at the Source - The cap is designed to distribute load from intersecting beams to the column below, with defined limits for side beam download (maximum 40% of download, not to exceed 10,665 lb.) so structural designers have clear, usable parameters to work with.

Specifications

• Manufacturer Part Number (MPN): ECCL3 1/4X
• Brand: Simpson Strong-Tie
• Beam Width: 3-1/8"
• 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 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 beams to column at end-of-beam intersections
• Projects with specific beam and post size combinations as determined by a designer
• Applications requiring field welding to a steel column (available without column straps - specify "No Straps" when ordering)

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.
• Simpson Strong-Tie Gray paint (Also available in HDG - Contact us for Quote)

Frequently Asked Questions

What beam width is the ECCL3 1/4X designed to fit?

The ECCL3 1/4X is specifically designed for a 3-1/8" beam width. It is important to verify your beam dimensions before installation to ensure a proper fit and reliable structural connection.

What type of application is the L-shape end configuration intended for?

The L-shape end configuration is purpose-built for end-of-beam applications where two beams meet in an "L" formation on top of a column. This makes it well suited for corner or end-of-run structural connections rather than interior or inline column cap applications.

What material and finish does the ECCL3 1/4X use?

The ECCL3 1/4X is constructed from 7 gauge or 3 gauge steel depending on the size, and is finished with Simpson Strong-Tie Gray paint. A hot-dip galvanized (HDG) finish is also available for applications requiring enhanced corrosion resistance.

Can the ECCL3 1/4X be customized for different beam and post size combinations?

Yes. Many combinations of beam and post sizes can be manufactured to meet specific project requirements, making the ECCL3 1/4X adaptable to a variety of structural configurations beyond the standard offering.
