Key Features
L-Shaped Beam Support Built for end-of-beam connections where two 6x beams meet in an L formation over a 6x post. That gives you a purpose-built connection instead of piecing together hardware that was not made for this layout. 7-Gauge Steel Build Heavy-gauge steel, certified welds, and an extended seat area give this connector the strength and bearing surface needed for serious structural work. Faster SDS Installation The Simpson Strong-Tie L-Shape End Column Cap for 6x Beams, 6x Post w/ SDS Screws, Skewed Right (ECCLRQ666SDS) includes Strong-Drive SDS connector screws for a faster install and a lower-profile connection than standard through bolts.
Overview
The Simpson Strong-Tie L-Shape End Column Cap for 6x Beams, 6x Post w/ SDS Screws, Skewed Right (ECCLRQ666SDS) is a structural framing connector made for end-of-beam column-to-beam connections. This is a column cap designed for joining two 6x beams in an L formation over a 6x post. Model Number: ECCLRQ666SDS. If you are building a beam-to-post connection that needs the right-side skewed layout, this hardware gives you the geometry, material thickness, and fastener pattern to do the job with a purpose-built bracket instead of field improvising.
What matters here is the application. This connector is meant for end-of-beam situations where the beam layout turns the corner on top of a post. The right-skewed configuration is not just a minor detail. It determines the direction the side beam lands, so ordering the correct orientation saves time and avoids a bad fit on site. Simpson also calls out that the left-hand version is a different model, which tells you this piece is application-specific, not a universal bracket.
The construction is straightforward and job-relevant: 7-gauge steel, certified welds, and a gray paint finish. The heavy steel matters because this part is carrying structural load and distributing it from the beams into the post. The extended column seat adds bearing area, which helps support the connection where the beams land. Certified welds matter for the same reason. On a connector like this, weld quality is not cosmetic. It is part of how the bracket handles load and holds alignment.
This model uses Strong-Drive SDS heavy-duty connector screws instead of standard through bolts, and the screws are included. That is a practical advantage on the job. You get faster installation, less hardware sticking out, and a cleaner connection profile. Tool Nut shoppers looking for a framing bracket that cuts down installation time without moving away from a published connector system will appreciate that this hardware was designed around those screws from the start.
There are also a couple of small design details that make real installation easier. Diamond holes are provided for temporary fastening during setup, which helps hold position while you get the connector seated and square. Simpson also specifies installing the 1/4 inch by 2-1/2 inch SDS screws in all round holes to achieve published load values. In plain terms: the hole pattern is part of the engineering, so using the right fasteners in the right holes is what gets you the performance this connector is built for.
In terms of use, this Simpson Strong-Tie framing bracket fits nominal 6x members: 6x main beam, 6x side beam, and 6x post. That makes it a good fit for heavy timber-style wood construction, outdoor structures, deck framing details, and other wood-to-wood structural connections where an L-shaped beam layout lands on a post. If your job involves new construction or retrofit work and you need a beam/post connector built for this exact corner condition, this is the right kind of hardware to be looking at.
Who should buy it? Builders, framers, deck contractors, and serious DIY users working from engineered plans or code-driven structural details. This is not a general-purpose bracket. It is a specific structural connector for a specific beam-to-post condition. If that matches your layout, it is the cleaner and faster way to handle the connection. If your beam direction is opposite, you need the left-skew version instead.
Built for a Specific Structural Layout
This connector is made for one job: supporting a right-skewed L-shaped beam connection over a 6x post. That kind of application-specific hardware saves guesswork and keeps the framing detail aligned with the intended connection design.
- Fits nominal 6x main beam, 6x side beam, and 6x post
- Right-direction layout for end-of-beam L connections
Heavy Steel Where It Counts
On structural connectors, thickness and weld quality are not side notes. This one uses 7-gauge steel with certified welds and an extended seat area to give the beams more bearing surface at the connection.
- Made from 7-gauge steel
- Certified welds for strength and loading confidence
Faster Install With Included SDS Screws
The included Strong-Drive SDS heavy-duty connector screws help speed up installation compared to standard through-bolt methods, while keeping the finished connection lower in profile.
- Includes 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws
- Diamond holes allow temporary fastening during setup

Pro Tip
Use the diamond holes only to hold the connector in place during setup. For the rated connection, Simpson calls for the 1/4 inch by 2-1/2 inch SDS screws in all round holes, so do not treat the temporary holes as your finished fastener pattern.
Tool Nut’s Take
Tool Nut’s Take
Simpson Strong-Tie ECCLRQ666SDS Is the Right Fix for a Very Specific Connection
If your plans call for a right-skewed 6x beam-to-6x post L connection, this is the kind of hardware you buy once and install with confidence.
- Who it’s for: Framers, deck builders, and contractors handling structural wood connections with 6x members.
- Why it stands out: 7-gauge steel, certified welds, included SDS screws, and a purpose-built right-hand layout make it faster and cleaner than trying to make a generic bracket do a specialized job.
- Worth knowing: This is not a universal column cap. Orientation matters, so make sure you need the skewed-right version before you order.
Common Questions
- What size members does this connector fit? It is designed for nominal 6x beam and 6x post connections, including a 6x main beam, 6x side beam, and 6x post.
- Is this the left or right version? This is the skewed-right model. If your layout requires the opposite orientation, Simpson lists the ECCLLQ model for left direction.
- What fasteners does it use? It uses 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws.
- What is it made from? The connector is made from steel and uses a gray paint finish.
