The Simpson ECCLQM5.50G-KT is a 5-1/2 in. L-shape end column cap engineered for raised pier foundations and heavy-timber construction where large beams bear directly on concrete or concrete block (CMU) columns. Intended specifically for building corner connections, this embedded column cap pairs a heavy-gauge beam seat with Simpson Strong-Tie SSTB anchor bolts to deliver the high uplift and lateral resistance required in high-wind regions. The hot-dip galvanized (HDG) finish makes it a reliable choice for exterior environments and pressure-treated lumber applications. The kit ships complete with MSTQM straps and Strong-Drive SDS Heavy-Duty Connector screws, so everything needed for a code-conscious corner connection is included right out of the box.

Key Features

• Included MSTQM straps - provide a direct, engineered connection from the column cap to the wall framing, eliminating the need to source additional strap hardware separately.
• SDS screws configured for high uplift design values - fasten the assembly to resist the vertical and lateral forces generated during high-wind events, supporting structural integrity at critical corner locations.
• Certified welds - give builders and inspectors confidence in the strength and loading capacity of the fabricated connection, simplifying job-site approval.
• SSTB offset design - allows flush installation to the edge of the pier so the column cap sits tight to the masonry face without requiring field modification.
• SSTBs spaced to fit standard CMU cells - drop directly into standard concrete masonry unit block cells, reducing layout time and the risk of anchor placement errors.
• 7 gauge steel construction - delivers heavy-gauge strength at the beam seat where load transfer demands are highest in post-and-beam and raised pier foundation systems.
• Hot-dip galvanized (HDG) finish - provides extra corrosion resistance compared to standard coatings, making this cap well suited for exterior installations and contact with treated lumber.
• Included Strong-Drive SDS Heavy-Duty Connector screws require no pre-drilling - speed up installation and feature a corrosion-resistant double-barrier coating that holds up in the same demanding environments as the cap itself.

Why This Product

• A complete corner connection kit - the included MSTQM straps and Strong-Drive SDS screws mean the full fastening system for a building corner pier connection arrives in a single kit, reducing trips to the supplier and the chance of missing hardware on the job site.
• Engineered specifically for high-wind and heavy-timber demands - the combination of a heavy-gauge beam seat, certified welds, and SSTB anchor bolts produces the high uplift and lateral resistance that pier foundation corners require in wind-prone construction zones.
• Designed to work with standard CMU construction - SSTB spacing matched to standard concrete masonry unit cells and a flush-to-edge offset means this cap integrates cleanly into masonry pier work without field cutting or custom anchor layouts.
• Hot-dip galvanized for long-term exterior performance - the HDG finish is suited for the corrosive conditions common to exterior foundation details and treated-wood applications, helping protect the structural connection over the life of the building.
