The Simpson End Column Cap 6-3/4 x 6-3/4 Rotated Straps with SDS2.5 Screws is engineered for end-of-beam column-to-beam connections in wood construction, delivering reliable structural performance where heavy timber and engineered lumber meet. Designed by Simpson to handle demanding post and beam framing applications, this end column cap features rotated straps and an extended bearing seat, making it a dependable choice for projects requiring enhanced uplift resistance under seismic or high-wind loading conditions.

Key Features

• Rotated Strap Configuration - positions the straps to suit end-of-beam applications specifically, giving builders a connector designed for the geometry of their actual installation rather than a generic cap adapted for the purpose.
• Extended Bearing Seat - provides additional bearing surface area beyond the side of the column, helping distribute load from the beam more effectively and adding critical support at the connection point.
• 3-Gauge Steel Construction - delivers the structural rigidity and strength needed for heavy timber framing, so the connection performs reliably under demanding loads over the long term.
• Simpson Strong-Tie Gray Paint Finish - provides a consistent, durable surface treatment that complements other Simpson hardware used throughout a project.
• Includes 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws - attaches to a greater net section area of the column than bolt attachment normally allows, speeding installation while maintaining high connection strength at both the beam and post.
• Approved for Seismic and High-Wind Applications - rated for enhanced uplift resistance, making it a code-appropriate choice for structures in earthquake zones or hurricane-prone regions.

Why This Product

• Purpose-built for end-of-beam conditions - the rotated strap design addresses the specific geometry of end column installations, so builders get a connector engineered for their application rather than a standard cap pressed into service.
• Screw-based fastening covers more net section area - Strong-Drive SDS screws engage a greater portion of the column cross-section compared to bolt attachment, translating to a stronger, more efficient connection with faster installation.
• Verified uplift performance for high-demand environments - approved for seismic and high-wind loading applications, this column cap supports structural reliability in regions where uplift forces are a primary design concern.
• Fits 6-3/4 in. engineered lumber and heavy timber columns - sized precisely for glulam and other engineered lumber profiles common in modern timber framing, reducing guesswork and ensuring a correct, secure fit.

Frequently Asked Questions

What size column is this end column cap designed to fit?

The ECCQ77SDS2.5ROT is designed to fit a 6-3/4" x 6-3/4" column, making it suited for heavy timber and engineered lumber applications of that dimension.

What does "rotated straps" mean on this column cap?

The rotated straps on the ECCQ77SDS2.5ROT are oriented 90 deg. from a standard configuration, which provides flexible installation options depending on the specific framing layout and end-of-beam application requirements.

What fasteners are included, and why are SDS screws used instead of through bolts?

The ECCQ77SDS2.5ROT comes with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws. These screws offer a lower profile than standard through bolts and attach to a greater net section area of the column than bolt attachment normally allows, resulting in a strong, efficient connection.

What material and finish is used on this column cap?

The ECCQ77SDS2.5ROT is constructed from heavy-duty 3-gauge steel and finished with Simpson Strong-Tie Gray paint, providing durability suitable for wood construction applications.
