The Simpson End Column Cap Kit Right L-Shape for GFCMU and Concrete Piers HDG ECCLRQMD5.50G-KT is a hot-dip galvanized embedded column cap kit engineered by Simpson for raised pier foundation systems where heavy beams bear down on concrete or concrete masonry unit columns. The right-hand L-shape configuration provides a corner seat that supports a third structural member at the connection point, making it well suited for perimeter deck joist and beam attachment at column corners. Paired with MSTQM straps and screws, the kit arrives ready for high-uplift, high-lateral-resistance corner connections designed to help structures perform under high-wind conditions.

Key Features

• Right-hand L-shape configuration - positions a corner seat that accommodates a third structural member, allowing perimeter deck joists or beams to tie in cleanly at the column corner without additional fabrication.
• Hot-dip galvanized finish on the column cap - delivers corrosion resistance suited to outdoor and exposed pier foundation environments where long-term durability is critical.
• 7-gauge steel construction - provides the heavy-gauge strength needed to transfer the significant loads generated when large beams rest on concrete or CMU columns.
• SSTB anchor bolt offset design - enables flush installation to the edge of the pier, and SSTB spacing aligns with standard CMU cell layouts for straightforward field installation without custom drilling patterns.
• Kit includes MSTQM straps and screws - delivers a complete, code-ready corner connection in a single package, reducing trips to the supplier and keeping the installation on schedule.
• Engineered for uplift and lateral resistance - the high uplift design values achieved through the included screw configuration help structures resist the forces generated during high-wind events.
• Domestically produced - the column cap originates from the United States, supporting consistent quality standards expected on engineered structural hardware.

Why This Product

• A complete corner connection solution - rather than sourcing the cap, straps, and fasteners separately, buyers receive the embedded column cap, MSTQM straps, and screws together, simplifying procurement and reducing the chance of mismatched components on the job site.
• Purpose-built for raised pier and CMU applications - the L-shape geometry and SSTB-compatible offset design address the specific geometry challenges of flush edge-of-pier installations and standard CMU cell spacing, saving layout time in the field.
• Handles both a primary beam and a third member simultaneously - the corner seat supports perimeter deck joists or additional beams at the same connection point, eliminating the need for supplemental hardware to manage the third structural member.
• Hot-dip galvanized protection on exposed structural hardware - for column caps that live at or near grade in pier foundation systems, a hot-dip galvanized finish provides a meaningful level of corrosion resistance that bare or lightly coated steel cannot match in these conditions.

Installation

Install 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws as specified. MSTQM straps connect the ECCLQMD to the wall framing. The SSTB offset design enables flush installation to the edge of the pier, and SSTB spacing is designed to align with standard CMU cells for straightforward field installation.

Options

• Contact us for Configurable Options and Special orders
• Available in widths up to nominal 7-1/8" width.
• For variable widths on side stirrups, specify W3 (3 1/4" to 7 1/8") and add an "X" to the end of the core model name. Example: ECCLQMD5.50GX-KT, W3 = 3 5/8".
• ECCLQMD is available in left or right side beam orientations. Specify ECCLLQMD or ECCLRQMD.

Frequently Asked Questions

What type of foundation or pier is this column cap designed for?

This column cap is engineered specifically for raised pier foundations, including concrete and concrete block (CMU) columns. The SSTB anchor bolts are spaced to fit standard CMU cells, and the SSTB offset allows for flush installation to the edge of the pier.

What makes this an "L-shape" kit, and what advantage does that provide?

The L-shape configuration features a corner seat that supports a third member at the connection point. This makes the kit particularly well suited for attaching perimeter deck joists or beams at corners, in addition to the main beam connection.

What components are included in this kit?

The kit includes the ECCLRQMD5.50G embedded column cap, MSTQM straps, and screws. These components work together to provide a complete, code-ready corner connection, with the MSTQM straps connecting the ECCLQMD to the wall framing and the screws configured to deliver high uplift design values.

What material and finish is used on this column cap, and what steel gauge is it made from?

The column cap is constructed from heavy 7-gauge steel and features a hot-dip galvanized finish for corrosion resistance. It is made in the United States and includes certified welds for confidence in strength and loading.
