The Simpson ECC46PC Black End Column Cap is a heavy-duty structural connector from Simpson built specifically for end-of-beam column-to-beam connections in wood construction. Engineered to pair a 4X beam with a 6X post, this end column cap features a seat that extends beyond one side of the column to deliver additional bearing surface area, distributing load effectively while providing critical structural support at the connection point. Finished in a durable black powder-coat over 7-gauge steel construction, it is well suited for structural framing applications where reliable load transfer and code-compliant performance are priorities.

Key Features

• Certified welds - give you confidence that every joint meets consistent strength standards, reducing uncertainty during inspection and installation
• Increased uplift load capacity - engineered to handle the heightened demands of earthquake and wind loading, making this cap appropriate for projects in high-load environments
• NDS code-compliant bolt spacing - simplifies the approval process on permitted structural framing projects by meeting established code requirements out of the box
• Extended seat bearing surface - projects beyond one side of the column to distribute beam load more broadly, reducing stress concentration at the connection
• 7-gauge steel construction - provides the structural integrity needed for demanding column cap applications without requiring an upgrade to heavier hardware
• Black powder-coat finish - delivers a clean, finished appearance that suits exposed timber framing while adding a layer of surface protection
• Made in the United States - produced domestically, which can support project sourcing requirements and quality expectations on commercial and residential builds alike

Why This Product

• Purpose-built fit for 4X beam and 6X post combinations - rather than adapting a general-purpose connector, you get a cap sized and engineered specifically for this lumber pairing, reducing guesswork and improving installation accuracy
• Handles wind and seismic uplift demands - with uplift loads increased beyond standard column cap performance, this connector is a practical choice for structures in regions where wind or earthquake loading governs the design
• Simplifies code compliance - NDS-compliant bolt spacing means your connection detail is already aligned with widely referenced framing standards, saving time during plan review and field inspection
• Structural reliability from a trusted connector brand - Simpson has long been a reference standard in structural wood connectors, and the ECC46PC carries that same commitment to certified weld quality and load-rated performance into end-of-beam applications

Frequently Asked Questions

What beam and post sizes is the ECC46PC compatible with?

The ECC46PC is designed for use with a 4X beam and a 6X post, making it specifically suited for end-of-beam column-to-beam connections in wood construction where those lumber dimensions are used.

What fasteners are required to install the ECC46PC?

Installation requires 5/8" machine bolts - two for the beam and two for the post. The bolt spacing is designed to meet NDS code requirements for optimal performance.

What material and finish does the ECC46PC feature?

The ECC46PC is fabricated from 7-gauge steel and finished with a durable black powder-coat. This finish provides a clean, finished appearance suited for visible structural applications.

What makes the ECC46PC seat design beneficial for structural connections?

The seat of the ECC46PC provides additional bearing surface area that extends beyond one side of the column. This design helps distribute the load from the beam and provides critical support for the connection, which is particularly important in end-of-beam applications.
