The Simpson Strong-Tie ECCL3 1/4X is an L-shape end column cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. Designed for a 3-1/8" beam width, this heavy-duty column cap helps distribute load from the beams and provides critical structural support at the connection point. Built with certified welds and bolt spacing that meets NDS code requirements, the ECCL3 1/4X is a trusted solution for demanding structural applications requiring precision-engineered column cap hardware.

Key Features

• Certified Welds: Provides confidence in strength and load performance at every connection point.
• NDS Code-Compliant Bolt Spacing: Bolt spacing meets NDS code requirements to ensure optimal structural performance.
• Diamond Holes: Included to allow for temporary fastening during installation.
• L-Shape End Configuration: Purpose-built for end-of-beam applications where two beams meet in an "L" formation on top of a column.
• Load Distribution: Designed to distribute beam loads and support the connection when properly installed.
• Multiple Size Combinations: Many combinations of beam and post sizes can be manufactured to meet specific project requirements.

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)

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.
