The Simpson 5-1/8 in. Beam 6x Post End Column Cap with Rotated Straps is a Simpson engineered connector built for reliable column-to-beam connections at end-of-beam positions in wood construction. Fabricated from heavy 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this column cap pairs an extended bearing seat with a full complement of included Strong-Drive SDS Heavy-Duty Connector screws, delivering a structurally efficient and installation-ready solution for timber framing, post-and-beam assemblies, and similar load-bearing applications.

Key Features

• End-of-beam column cap configuration - purpose-built for end-of-beam positions where a standard interior cap cannot be used, ensuring proper load transfer at beam termination points without compromising structural integrity.
• Extended bearing seat design - distributes beam loads beyond the side of the column, increasing the bearing surface area and reducing concentrated stress at the connection point for a more reliable structural outcome.
• Rotated strap orientation - straps are factory-rotated 90 deg. relative to the standard configuration, giving builders the flexibility to handle framing layouts where a conventional strap orientation would conflict with adjacent members.
• 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws included - all fasteners needed for both beam and post attachment come in the box, so installation can begin immediately without sourcing additional hardware separately.
• SDS screw fastening system - screws attach to a greater net section area of the column compared to standard through-bolt attachment, producing a strong, high-capacity connection with a lower-profile finished appearance.
• 3-gauge steel construction with Simpson Strong-Tie Gray paint finish - heavy-gauge material provides the structural robustness required for demanding load-bearing connections, while the factory-applied finish offers a consistent, professional look on exposed timber assemblies.
• Simpson engineering and United States origin - manufactured to the standards that structural contractors and building inspectors recognize, supporting code-compliance documentation and project approval confidence.

Why This Product

• Complete, ready-to-install package - the column cap ships with all 28 SDS screws required for full installation (14 for the beam, 14 for the post), eliminating a separate fastener purchase and keeping projects on schedule.
• Rotated strap geometry solves real framing challenges - when standard connector orientations conflict with adjacent structural members or architectural elements, the 90 deg. rotated straps provide a direct, code-supportable solution without field modification.
• High-capacity SDS fastening over conventional bolts - the Strong-Drive SDS screw installation engages a greater net section area of the post than through-bolts typically achieve, translating to a stronger column-cap connection with less material removal from the column.
• Heavy-gauge steel from a trusted structural brand - 3-gauge steel construction backed by Simpson engineering gives contractors and inspectors the material confidence needed for structural beam-to-post connections in demanding residential and commercial framing applications.

Frequently Asked Questions

What size beam is the ECCQ5-6SDS2.5ROT designed to work with?

This column cap is designed for a 5-1/8 in. wide beam, with a W1 dimension of 5-1/4 in. and a W2 dimension of 5-1/2 in. to accommodate the connection properly.

What fasteners are used to install this column cap, and are they included?

Installation uses 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws. A total of 28 screws are included - 14 for the beam and 14 for the post - so no additional fasteners need to be purchased separately.

Why are SDS screws preferred over standard through bolts for this connector?

The Strong-Drive SDS screws provide a lower profile than standard through bolts and attach to a greater net section area of the column, resulting in a strong, efficient connection with a cleaner finished appearance.

Is this column cap suitable for high-wind or seismic applications?

Yes. The ECCQ series features increased uplift load values specifically to meet the demands of earthquake and wind loading conditions, making it appropriate for use in high-load structural environments.
