The Simpson LCC6-3.5 Column Cap by Simpson is engineered specifically to be welded to the lally column and attach to the girder, delivering a higher-capacity column-to-beam connection for new or replacement applications. The cap fits over the column for precise positioning before welding, and its side plates capture the beam, enabling a safer installation process than standard cap plates - making it a dependable solution for structural beam-to-post connections in both new construction and retrofit projects.

Key Features

• Cap fits over column for precise positioning and welding - eliminates guesswork during installation, keeping the connection properly aligned before it is permanently secured
• Side plates capture the beam - provides a safer installation process than standard cap plates, reducing the risk of beam movement during assembly
• Provides adequate bearing length for larger girder reactions - supports the heavy loads that quad 2x10 and quad 2x12 beam configurations demand, giving structural connections the capacity they need
• 12-gauge steel construction - delivers the strength and rigidity required for high-capacity column-to-girder connections in demanding structural applications
• Simpson Strong-Tie gray paint finish - provides a durable protective coating that helps resist corrosion in typical interior structural environments

Why This Product

• Purpose-built for lally column applications - designed specifically to work with 3-1/2 in. outside diameter lally columns, so the fit is engineered rather than adapted, ensuring a reliable structural connection every time
• Handles demanding load requirements - the 6-1/8 in. seat width provides adequate bearing length for larger girder reactions, making this cap well-suited for heavy-duty framing where load transfer cannot be compromised
• Simplifies a critical connection - the slip-over collar design positions the cap precisely on the column before welding, reducing installation complexity and improving accuracy compared to standard flat cap plates
• Versatile for new builds and replacements alike - equally effective in new construction and column replacement scenarios, offering contractors and builders a single go-to solution for high-capacity beam-to-post connections
