The Simpson LCC6-4 Column Cap is a Simpson Strong-Tie engineered steel connector designed specifically to be welded to the lally column and attach to the girder, delivering a higher-capacity column-to-beam connection for both new construction and replacement applications. Side plates capture the beam, enabling a safer installation process than standard cap plates - making this connector a dependable choice wherever a secure, load-bearing lally column-to-girder connection is required.

Key Features

• Fits over the column for precise positioning before welding - eliminates guesswork during placement, reducing installation errors and saving time on the job.
• Side plates capture the beam during installation - provides a safer, more controlled process compared to standard cap plates, improving jobsite safety.
• Provides adequate bearing length for larger girder reactions - supports heavy structural loads without compromising connection integrity, suitable for demanding framing applications.
• Compatible with quad 2x10 and quad 2x12 girder configurations - accommodates common multi-ply beam sizes used in residential and light-commercial framing.
• Constructed from 12-gauge steel with Simpson Strong-Tie gray paint finish - delivers durable, corrosion-resistant performance suited for structural column cap applications.
• Designed for both new and replacement applications - offers flexibility whether you are installing a new lally column assembly or upgrading an existing connection for greater capacity.

Why This Product

• Purpose-built for lally column connections - engineered specifically for 4 in. outer diameter lally columns, this cap provides a precise, reliable fit that generic column hardware cannot match.
• Higher-capacity connection in a single component - the design delivers a stronger column-to-beam joint than standard cap plates, making it well-suited for girder assemblies carrying significant structural loads.
• Safer installation by design - the side plates hold the beam in position during fastening, reducing the risk of shifting or misalignment compared to open cap plate alternatives.
• Versatile for new builds and retrofit projects - whether replacing a deteriorated column cap or completing new framing, this connector handles both scenarios without requiring a separate product.

Frequently Asked Questions

What column diameter is the LCC6-4 designed to fit?

The LCC6-4 is designed specifically to work with lally columns that have a 4 in. outer diameter. The cap fits over the column for precise positioning and welding.

What girder sizes are compatible with the LCC6-4?

The LCC6-4 is compatible with quad 2x10 and quad 2x12 beam configurations, with a seat width of 6-1/8 in. to provide adequate bearing length for larger girder reactions.

How is the LCC6-4 installed?

The cap is fitted over the lally column for precise positioning and then welded to the column. It attaches to the girder using 0.162 in. x 3-1/2 in. nails. The side plates capture the beam, enabling a safer installation process than standard cap plates.

Is the LCC6-4 suitable for replacement applications as well as new construction?

Yes. The LCC6-4 is designed for both new and replacement applications, providing a higher-capacity column-to-beam connection in either scenario.
