Product Description
The Simpson LCC3.5-3.5 Column Cap is a structural connector 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. Side plates capture the beam, enabling a safer installation process than standard cap plates - making this connector a reliable choice for residential and light-commercial framing projects where a secure, precise column-to-girder connection is critical.
Key Features
- Fits over the column for precise positioning before welding - reduces guesswork during installation and helps ensure accurate alignment every time
- Side plates capture the beam during installation - keeps the girder securely held in place for a safer, more controlled process compared to standard cap plates
- Provides adequate bearing length for larger girder reactions - supports heavier structural loads at the column-to-beam connection point
- Compatible with 3.5 in. LVL/PSL/LSL engineered lumber beams - pairs directly with today's most common engineered girder materials used in new construction and replacement work
- Constructed from 12-gauge steel with a Simpson Strong-Tie gray paint finish - delivers the structural rigidity and corrosion resistance expected from a load-bearing connector
Why This Product
- Purpose-built for lally column applications - unlike generic cap plates, this connector is designed specifically for use with lally columns, so the cap fits over the column precisely, simplifying both positioning and welding without improvised adjustments
- Enhanced safety during beam installation - the side-plate design actively captures the girder as it is set, reducing the risk of shifting or slipping that can occur with flat cap plates, which matters most when working with heavy engineered lumber
- Versatile fit for new builds and replacement projects - whether upgrading an aging column connection or framing a new structure, this cap is rated for both applications, making it a practical option for contractors and repair work alike
- Made in the United States by Simpson - backed by a brand widely trusted in structural connector engineering, this column cap meets the quality expectations required for load-path-critical connections in residential and light-commercial framing

Frequently Asked Questions
- What size lally column is this cap designed for?
- This column cap is designed specifically to work with lally columns that have a 3-1/2 in. outside diameter, providing a precise fit for accurate positioning and welding.
- What type of beam or girder is compatible with this column cap?
- The LCC3.5-3.5 is compatible with a 3.5 in. LVL/PSL/LSL beam or girder, with a seat width of 3-5/8 in. to provide adequate bearing length for larger girder reactions.
- How is the LCC3.5-3.5 installed?
- The cap is fitted over the lally column for precise positioning and then welded to the column. It is subsequently attached to the girder and installs with 0.162 in. x 3-1/2 in. nails. The side plates capture the beam, enabling a safer installation process than standard cap plates.
- What material and finish is used on this column cap?
- The LCC3.5-3.5 is made from 12-gauge steel and features a Simpson Strong-Tie gray paint finish for durability and corrosion resistance.
