The Simpson ECCLLQMD5.50G-KT is a heavy-duty, left-orientation end column cap engineered for raised pier foundations and structural applications where heavy beams bear down on concrete or concrete block columns. Designed with a unique L-shaped configuration, this kit incorporates an additional seat to support a third member at the corner connection - making it the ideal solution for attaching perimeter deck joists and beams. The heavy-gauge beam seat, combined with certified welds and Simpson Strong-Tie SSTB anchor bolt compatibility, delivers the high uplift and lateral resistance required to help structures withstand demanding high-wind events. Includes MSTQM straps and screws right out of the box for a complete, ready-to-install column cap kit.

Frequently Asked Questions

What makes this column cap an "L-shaped" design, and why does that matter?

The L-shaped configuration includes an additional seat that supports a third structural member at the corner connection. This makes it especially well-suited for attaching perimeter deck joists and beams where a standard straight column cap would not provide that extra bearing point.

Is this column cap compatible with both concrete piers and concrete block columns?

Yes. The ECCLLQMD5.50G-KT is engineered for use with both concrete and GFCMU (concrete masonry unit) columns. The SSTB offset allows flush installation to the edge of a pier, and the SSTBs are spaced to fit standard CMU cells.

What is included in the kit, and does it come ready to install?

The kit includes MSTQM straps and screws right out of the box. The MSTQM straps make the connection from the ECCLQMD to the wall framing, and the screws are configured to provide high uplift design values, making this a complete, ready-to-install assembly.

What finish does this column cap have, and is it suitable for outdoor or exposed environments?

The ECCLLQMD5.50G-KT features a hot-dip galvanized finish, which provides corrosion resistance for use in exposed or outdoor environments such as raised pier foundations and deck applications.
