The Simpson 5-1/8 in. Beam 4x Post End Column Cap with Rotated Straps is a heavy-duty connector engineered by Simpson for reliable column-to-beam connections in end-of-beam wood construction applications. The cap's extended seat provides additional bearing surface area that reaches beyond the side of the column, helping distribute beam loads and deliver robust structural support. Fabricated from 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this connector is designed for installations requiring enhanced uplift resistance, a lower fastener profile than standard through bolts, and a rotated strap orientation to accommodate unique framing configurations.

Key Features

• Extended seat bearing surface - reaches beyond the column face to distribute beam loads across a broader area, reducing stress concentration at the connection point
• Strong-Drive SDS Heavy-Duty Connector screws included - attach to a greater net section area of the column than bolt attachment normally allows, delivering superior holding strength without the bulk of standard through bolts
• Rotated strap orientation - accommodates unique or non-standard framing configurations where a conventional strap position would not work, expanding installation versatility
• 3-gauge steel construction with Simpson Strong-Tie Gray paint finish - provides the heavy-duty material thickness needed for structural post-to-beam connections subject to earthquake or wind loading
• Diamond holes for temporary fastening - allow the installer to position and hold the cap in place during layout before final screw installation, improving accuracy and reducing rework
• Certified weld integrity - supports applications where structural connections require verified weld quality as part of the design or inspection criteria

Why This Product

• Engineered for demanding uplift conditions - approved for applications requiring enhanced uplift resistance under earthquake or wind loading, making this column cap a practical choice for structurally critical post-to-beam connections
• Screw-driven installation with no bolting required - the included 1/4 in. x 2-1/2 in. Strong-Drive SDS screws provide a lower profile than standard through bolts while connecting to a greater net section area of the column, simplifying the installation process without sacrificing load performance
• Ready to install right out of the box - comes complete with 14 beam screws and 14 post screws so installers have every fastener needed on hand, eliminating a separate hardware purchase for a straightforward fit-up
• Rotated strap design solves framing layout challenges - where standard column cap strap positions conflict with adjacent framing members or architectural constraints, the rotated orientation offers a direct solution without custom fabrication

• End-of-beam column-to-beam connections in wood construction
• Applications requiring enhanced uplift resistance for earthquake or wind loading
• Post-to-beam connections where a lower fastener profile than standard through bolts is desired
• Structural connections where certified weld integrity is required
• Installations requiring rotated strap orientation for unique framing configurations

What's Included

• 1x ECCQ5-4SDS2.5ROT End Column Cap (Rotated Straps)
• 14x 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws (Beam)
• 14x 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws (Post)

Installation

Fasten with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. The SDS screws attach to a greater net section area of the column than a bolt attachment normally allows, providing superior holding strength and a lower profile than standard through bolts. Diamond holes are provided for temporary fastening during installation.

Frequently Asked Questions

What beam width and post size is this column cap designed for?

The ECCQ5-4SDS2.5ROT is designed for a 5-1/8 in. wide beam and a 4x post. The cap measures 5-1/4 in. at W1, 3-5/8 in. at W2, 8-1/2 in. in length, and 7 in. in height.

What does the "rotated straps" configuration mean for this column cap?

The rotated straps configuration means the straps are oriented at 90 deg. relative to a standard column cap, making the ECCQ5-4SDS2.5ROT specifically suited for end-of-beam installation where a versatile strap orientation is required.

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

This column cap uses Strong-Drive SDS Heavy-Duty Connector screws, which provide a lower profile than standard through bolts and attach to a greater net section area of the column. All required Strong-Drive SDS screws for both beam and post connections are included with the product.

What material and finish is the ECCQ5-4SDS2.5ROT made from?

The ECCQ5-4SDS2.5ROT is fabricated from heavy-duty 3-gauge steel and features a Simpson Strong-Tie Gray paint finish for durability. It is made in the United States and includes certified welds for confidence in strength and loading.
