The Simpson ECCLLQMD5.50-KT End Column Cap Left L-Shaped is a heavy-gauge steel connector engineered for raised pier foundation applications where substantial beams bear directly on concrete or concrete block (GFCMU) columns. Its L-shaped geometry creates a corner seat that simultaneously supports a main beam and a third member such as a perimeter deck joist or beam, making it the purpose-built choice for corner column connections that demand both uplift resistance and lateral load transfer. Finished in Simpson Strong-Tie Gray paint and configured for left-hand beam orientation, this kit arrives complete with MSTQM straps and screws so installers have everything required for a verified, code-conscious connection.

Key Features

• L-shaped corner seat design - supports a main beam and a third member at the same connection point, eliminating the need for additional hardware at critical perimeter and corner column locations
• Left-hand beam orientation - factory-configured geometry that matches left-side column cap applications precisely, reducing on-site modification and installation error
• 7 gauge steel construction - provides the structural mass needed to achieve high uplift and lateral resistance values at beam-to-column connections in high-wind regions
• Simpson Strong-Tie Gray paint finish - delivers corrosion resistance suited to the exposed conditions common in raised pier and pier foundation environments
• Kit includes MSTQM straps and screws - everything needed for a complete, uplift-rated connection ships together, reducing trips to the supplier and keeping the installation on schedule
• SSTB anchor bolt offset geometry - allows flush installation to the edge of the pier, and bolt spacing aligns with standard CMU cells for straightforward embedding without custom layout work
• Domestic production - manufactured in the United States, supporting consistent quality control and material traceability on every unit

Why This Product

• One connector handles a complex corner load path - the L-shaped configuration is specifically engineered to carry a main beam and a secondary member simultaneously at a single column cap, a task that would otherwise require multiple connectors and additional engineering coordination
• Designed for the toughest pier foundation conditions - approved for use on concrete and GFCMU (concrete masonry unit) piers and rated for high-wind uplift and lateral loads, making it a reliable choice where foundation connections are subject to the most demanding structural requirements
• A complete kit eliminates guesswork - the included MSTQM straps and screws are pre-selected and configured for high uplift design values, so the installer works from a verified hardware set rather than sourcing compatible fasteners separately
• Streamlined field installation on standard CMU piers - SSTB bolt spacing is coordinated with standard CMU cell layout and the cap installs flush to the pier edge, cutting layout time and keeping the connection detail clean and inspection-ready

Frequently Asked Questions

What types of columns or piers is this end column cap designed to work with?

The ECCLLQMD5.50-KT is engineered specifically for use with concrete block (GFCMU) columns and concrete piers, making it well-suited for raised pier foundation applications where heavy beams bear directly on these column types.

What does the L-shaped configuration allow that a standard end column cap does not?

The L-shaped corner design incorporates an additional seat at the corner connection, which allows the cap to simultaneously support a main beam and a perimeter deck joist or beam - effectively connecting a third member at the same location.

What is included in the kit, and does it provide everything needed for installation?

Yes, the kit arrives complete with MSTQM straps and screws, providing everything needed for a verified, code-compliant connection right out of the box. The screws are configured to provide high uplift design values, and the MSTQM straps make the connection from the ECCLLQMD to the wall framing.

What are the main beam and side stirrup width dimensions for this model?

The main channel width (W1) is 5 1/2 in., and the side stirrup widths (W3 and W4) are also 5 1/2 in. The main channel length (L1) is 16 1/2 in.
