The Simpson ECCLRQ666SDS L-Shape End Column Cap is engineered for end-of-beam structural connections where two beams meet in an "L" formation on top of a post or column. Built by Simpson Strong-Tie from heavy-duty 7-gauge steel with certified welds and a gray paint finish, this right-skew column cap is purpose-built to distribute beam loads evenly and deliver dependable support at the connection point. Included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws make installation faster and result in a lower profile than standard through bolts, helping structural professionals complete connections efficiently without sacrificing strength.

Key Features

• SDS screw configuration for high uplift resistance - fasteners are positioned to maximize uplift design values, giving the connection greater capacity to resist lifting forces at the column cap joint.
• Certified welds throughout - weld quality is verified to meet strength and load-bearing standards, so buyers can trust the connection's integrity in demanding structural applications.
• Diamond holes for temporary fastening - allow the cap to be held in position during layout and alignment before final fasteners are driven, reducing the chance of misalignment and saving time on the job.
• Right-skew side beam orientation - the side beam exits to the right, making this cap the correct choice for right-hand L-shape configurations; the ECCLLQ model serves left-hand orientations.
• Fits nominal 6x main beam, 6x post, and 6x side beam members - sized precisely for 6x lumber throughout, eliminating the guesswork of sizing and the need for additional brackets or braces at the connection.
• 7-gauge steel construction - heavy-gauge material provides the structural rigidity needed for load-bearing column-to-beam connections in permanent structures.
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and a baseline level of corrosion resistance for the connector in typical covered or semi-exposed installations.

Why This Product

• A complete fastening solution right out of the box - the included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws mean you have everything needed to complete the connection without separately sourcing compatible hardware.
• Designed specifically for L-shape end-of-beam applications - unlike general-purpose post caps, this connector is purpose-engineered for the precise geometry of two beams intersecting in an "L" formation on a single column, reducing improvised workarounds in the field.
• High uplift performance through screw placement - the screw pattern is configured to deliver high uplift design values, making this cap well suited for structural connections where wind uplift or tension loads are a design consideration.
• Streamlined installation with a lower-profile result - SDS screws drive faster and sit lower than traditional through bolts, meaning less time spent on installation and a cleaner finished connection with fewer protrusions.
