The Simpson LCC4.5-4 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. 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 reliable choice for securing heavy girder loads in residential and light commercial framing.

Key Features

• Provides adequate bearing length for larger girder reactions - supports heavier loads at the column-to-beam connection, reducing the risk of undersized bearing surfaces in demanding structural applications.
• Cap fits over the column for precise positioning and welding - self-locating design keeps the cap aligned during installation, minimizing the chance of misalignment before the weld is set.
• Designed specifically to work with 4 in. outer diameter lally columns - purpose-built fit means no guesswork or field modifications when working with standard round steel lally columns.
• Side plates capture the beam - holds the girder securely in place during fastening, improving jobsite safety compared to flat cap plates that offer no lateral restraint.
• Compatible with triple 2x10 and triple 2x12 beams - accommodates the wide, built-up girder sizes commonly used to carry significant floor loads in residential framing.
• Made from 12-gauge steel - heavy-duty material thickness delivers the structural integrity required for load-bearing column cap applications.
• Simpson Strong-Tie gray paint finish - factory-applied coating helps protect the steel connector during handling, storage, and installation.

Why This Product

• Purpose-built for lally column connections - unlike generic cap plates, this connector is designed specifically for round steel lally columns, delivering a higher-capacity connection that meets the demands of new builds and retrofit projects alike.
• Safer, more controlled installation - the self-locating collar and beam-capturing side plates work together to keep components aligned and stable throughout the installation process, reducing the hazards associated with handling heavy girders overhead.
• Handles larger girder reactions - the 4-5/8 in. seat width provides the bearing area needed to distribute significant loads from triple 2x10 or triple 2x12 girders without overstressing the connection point.
• American-made quality from a trusted connector brand - built to Simpson's manufacturing standards in the United States, this column cap carries the consistency and quality control that structural professionals rely on for critical load-path connections.
