The Simpson ECC88 8x Beam 8x Post End Column Cap is a heavy-gauge structural connector engineered for end-of-beam column-to-beam connections in wood construction. Designed specifically for nominal 8x beam and 8x post applications, this end column cap features an extended bearing seat that distributes load beyond one side of the column, providing a strong and stable connection at column ends. Finished with Simpson gray paint and constructed to exacting standards, the ECC88 is a dependable choice for heavy timber framing and structural applications where elevated uplift resistance is required. Key Features Extended Bearing Seat - The seat of the column cap extends beyond one side of the column, increasing the bearing surface area so beam loads are distributed more effectively across the connection point. Enhanced Uplift Load Capacity - Engineered to accommodate elevated uplift loads, making this connector well-suited for structural connections in seismic zones and high-wind regions where uplift forces are a critical design consideration. Certified Weld Construction - Weld-certified fabrication gives builders and engineers confidence in the connector's strength and load-bearing integrity throughout the life of the structure. Heavy-Gauge Steel Construction - Built from 3 gauge steel for robust structural performance in demanding heavy timber framing applications. Simpson Gray Paint Finish - The factory-applied finish provides a consistent, professional appearance and helps protect the connector during handling and installation. Domestically Produced - Built to the quality standards associated with Simpson production, giving contractors assurance of consistent fabrication tolerances and material quality. Why This Product Purpose-Built for 8x Heavy Timber Connections - Unlike general-purpose column caps, the ECC88 is sized specifically for nominal 8x beam and 8x post combinations, eliminating guesswork and ensuring a precise, code-appropriate fit in heavy timber framing projects. Handles Seismic and High-Wind Uplift Demands - The enhanced uplift load ratings make this end column cap a practical solution for projects in areas subject to earthquake or high-wind conditions, where standard connectors may fall short of engineering requirements. Engineered for End-of-Beam Applications - The extended bearing seat design is specifically developed for end-of-beam column-to-beam junctions, providing the structural support and load distribution that a mid-span connector cannot replicate in this position. Configurable for Non-Standard Lumber - Straps may be rotated 90 deg. and optional dimension adjustments are available for special or rough-cut lumber sizes, giving design professionals flexibility to adapt the connector to project-specific requirements.

Options Contact us for Configurable Options and Special orders Straps may be rotated 90 deg. (see SPECS) For special, custom or rough-cut lumber sizes, provide dimensions. An optional W2 dimension may be specified. (The W2 dimension on straps rotated 90 deg. is limited by the W1 dimension.) Note: Product dimensions may differ from picture. Frequently Asked Questions What beam and post sizes is the ECC88 designed to fit? The ECC88 End Column Cap is designed for use with 8x beams and 8x posts, making it specifically suited for column-to-beam connections using nominal 8-inch lumber in both orientations. What fasteners are required to install the ECC88? The ECC88 requires two 3/4-inch machine bolts for the beam connection. Bolt spacing is designed to meet NDS code requirements to ensure optimal structural performance. What makes the ECC88 suitable for end-of-beam applications specifically? The ECC88 features an extended bearing surface where the cap seat extends beyond one side of the column. This design improves load distribution from the beam to the post, making it well-suited for end-of-beam column connections rather than interior mid-span locations. What material and finish is the ECC88 made from? The ECC88 is fabricated from 3-gauge steel for heavy-duty strength and durability, and it is finished with Simpson Strong-Tie gray paint. It also features certified welds to provide confidence in its strength and load capacity.
