The Simpson Strong-Tie ECCLRQ HDG L-Shape End Column Cap is engineered to create strong, reliable column-to-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. With a right-hand side beam orientation and support for 6x main beam, 6x post, and 6x side beam configurations, this cap helps distribute load from the beams and provides critical structural support at the connection point. Built from 7-gauge steel with a hot-dip galvanized finish, it is well suited for exterior structural applications and pressure-treated lumber projects. Included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws enable faster installation and a lower profile than standard through bolts.

Key Features

• SDS screw configuration optimized for uplift - screws are arranged to deliver high uplift design values, giving structural connections the holding strength needed in demanding load conditions.
• Certified welds throughout - factory-certified weld quality provides confidence in overall strength and load performance, reducing uncertainty on the job site.
• Diamond holes for temporary fastening - allow the cap to be held in position during layout and alignment before final fastening, making installation more manageable.
• Right-hand side beam orientation - designed specifically for right-side beam configurations at the column cap, ensuring a proper fit without field modification; the ECCLLQ model is available for left-hand orientation.
• 7-gauge steel construction - heavy-gauge material provides the structural rigidity and load capacity required for timber-framed column-to-beam connections.
• Hot-dip galvanized coating - offers extra corrosion resistance compared to standard finishes, making this cap suitable for exterior applications and use with pressure-treated lumber where moisture and chemical exposure are concerns.
• Includes Strong-Drive SDS Heavy-Duty Connector screws - the required fasteners arrive with the cap, so installation can begin without sourcing hardware separately, and the low-profile screw head avoids the bulk of standard through bolts.

Why This Product

• Purpose-built for L-formation beam connections - rather than adapting a generic bracket, this cap is specifically designed for end-of-beam applications where two beams meet in an "L" on top of a column, providing a cleaner, more structurally sound solution for that exact configuration.
• Hot-dip galvanization for long-term exterior performance - the HDG finish delivers a higher level of corrosion protection than standard coatings, making this cap a dependable choice for outdoor structures and connections involving pressure-treated wood where corrosive conditions are a real concern.
• Faster installation with included fasteners - the included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws drive faster than traditional through bolts and sit at a lower profile, reducing installation time while keeping the connection tight and clean.
• Engineered for confidence in structural loading - certified welds and a screw pattern configured for high uplift design values mean this cap is not just a connector but a load-distributing component built to perform under the stresses of real structural applications.

Frequently Asked Questions

What beam and post sizes is this column cap designed for?

The ECCLRQ666SDSHDG is designed for nominal 6x main beam, 6x post, and 6x side beam configurations, making it suitable for end-of-beam applications where two beams meet in an "L" formation on top of a column.

What fasteners are required, and are they included?

This column cap installs using 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212), which are included with the product. These screws provide faster installation and a lower profile than standard through bolts.

Is this column cap suitable for exterior or treated-wood applications?

Yes. The ECCLRQ666SDSHDG features a hot-dip galvanized (HDG) finish, which offers extra corrosion resistance, making it well suited for exterior and treated-wood applications.

What is the difference between the ECCLRQ and ECCLLQ models?

The difference is the side beam orientation. The ECCLRQ666SDSHDG has the side beam oriented to the right. If you need the side beam oriented to the left, you should order the ECCLLQ model instead.
