The Simpson LCC3.5-4 Column Cap by Simpson is engineered specifically to be welded to the lally column and attach to the girder, providing a higher-capacity column-to-beam connection for new construction or replacement applications. Side plates capture the beam, enabling a safer and more controlled installation process than standard cap plates - making this a reliable solution for structural basement and load-bearing column connections.

Key Features

• Fits over the column for precise positioning before welding - eliminates guesswork during placement, reducing the risk of misalignment on the job site
• Side plates capture the beam during installation - delivers a safer process than standard cap plates, keeping the beam securely in position while fastening
• Provides adequate bearing length for larger girder reactions - supports heavier structural loads where a standard cap would fall short
• Designed specifically for 4 in. outer diameter lally columns - purpose-built fit means no improvised adapters or compromised connections
• Accepts 3.5 in. LVL/PSL/LSL engineered lumber beams - compatible with today's most common engineered wood girder sizes used in residential framing
• Constructed from 12-gauge steel - provides the structural rigidity required for dependable column-to-beam load transfer
• Simpson Strong-Tie gray paint finish - adds a protective coating suited for the demanding conditions of structural applications

Why This Product

• Purpose-built for lally column connections - unlike generic cap plates, this fitting is designed from the ground up for lally column installations, delivering a precise fit and a more secure column-to-girder connection for both new builds and retrofit projects
• Safer installation through smarter design - the side-plate design actively captures the beam during fastening, reducing the chance of shifting or dropping compared to flat cap plate alternatives, which matters when working in tight basement or crawl space conditions
• Higher-capacity load path - the seat geometry provides adequate bearing length for larger girder reactions, making this cap suitable for demanding structural scenarios where load transfer cannot be compromised
• Made in the United States by a trusted structural connector brand - Simpson engineered this cap to meet the performance expectations of contractors and builders who rely on consistent, code-compliant hardware for load-bearing applications

Frequently Asked Questions

What size lally column is the LCC3.5-4 designed to work with?

The LCC3.5-4 is designed specifically to work with lally columns that have a 4 in. outer diameter. The cap fits over the column for precise positioning prior to welding.

What type of girder or beam is compatible with this column cap?

This column cap is compatible with a 3.5 in. LVL/PSL/LSL beam. The seat width of 3-5/8 in. provides adequate bearing length for larger girder reactions.

How is the LCC3.5-4 installed?

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

What material and finish is the LCC3.5-4 made from?

The LCC3.5-4 is constructed from 12-gauge steel and features a Simpson Strong-Tie gray paint finish for durability and corrosion resistance in structural applications.
