The Simpson ECCLR464 L-Shape End Column Cap is an engineered structural connector from Simpson Strong-Tie designed to provide strong, reliable column-to-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. Built from heavy-duty 7-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, this right-hand configuration accommodates a 4x main beam, 6x post, and 4x side beam combination - making it a precise, load-distributing solution for deck framing, pergola construction, and timber-frame projects where structural integrity and code compliance matter most.

Key Features

• Certified welds - assembled to verified weld standards, giving you confidence in the connector's strength and load-handling performance at every joint
• NDS code-compliant bolt spacing - bolt hole layout meets National Design Specification requirements, helping your installation pass inspection without additional field modifications
• Diamond holes for temporary fastening - allow you to hold the cap in position during layout and alignment before final bolting, reducing the chance of misplacement on the job
• Right-hand (skewed right) orientation - purpose-built geometry for right-direction L-shape end-of-beam applications; order the ECCLL for left-direction configurations
• Nominal member sizing for 4x main beam, 6x post, and 4x side beam - sized to specific plan details so the cap fits the intended members without guesswork or field adaptation
• 7-gauge steel construction - heavy-gauge material delivers the structural mass needed to distribute beam-to-post loads in demanding outdoor and timber-frame applications
• Simpson Strong-Tie gray paint finish - factory-applied coating provides a consistent, clean appearance and a baseline level of protection suited to structural connector use

Why This Product

• Engineered specifically for L-shape end-of-beam connections - unlike generic brackets, the ECCLR464 is purpose-designed for the exact geometry where two beams meet at a right-angle "L" on top of a column, eliminating the need for additional brackets or braces at that connection point
• Certified welds and NDS-compliant bolt spacing built in - structural confidence and code compliance are designed into the connector itself, so builders spend less time engineering workarounds and more time moving the project forward
• Sized to match your plan details precisely - because end column caps are sized to accommodate the many combinations of beam and post sizes, this connector aligns directly with the 4x main beam, 6x post, and 4x side beam members called out in common deck and timber-frame plans
• Made in the United States with Simpson Strong-Tie quality standards - domestic fabrication under a trusted structural connector brand means consistent material and weld quality on every unit

Approved Applications

The ECCLR464 is engineered for use in structural applications where two beams meet at a right-angle "L" formation at the end of a column. Typical uses include:

• Deck framing and outdoor structure beam-to-post connections
• Pergola and arbor timber frame construction
• End-of-beam column cap applications requiring a right-skewed L-shape configuration
• Any structural application requiring a strong, load-distributing connection between a 4x main beam, 6x post, and 4x side beam

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).

Frequently Asked Questions

What beam and post sizes does the ECCLR464 accommodate?

The ECCLR464 is sized for a 4x main beam, a 6x post, and a 4x side beam. These are nominal member sizes, and the cap is purpose-built for this specific combination to ensure a proper structural fit.

What is the difference between the ECCLR464 and the ECCLL model?

The ECCLR464 is a right-hand configuration, meaning the side beam extends to the right when viewed from the front. If your project requires a left-hand orientation, you would need to order the ECCLL model instead.

What fasteners are required to install the ECCLR464?

The ECCLR464 should be installed with 5/8-inch diameter bolts. The bolt spacing is designed to meet NDS code requirements to ensure optimal structural performance.

What material and finish is the ECCLR464 made from?

The ECCLR464 is constructed from heavy-duty 7-gauge steel and features a factory-applied Simpson Strong-Tie gray paint finish. It is assembled with certified welds for confidence in strength and loading performance.
