The Simpson LCC7-3.5 Column Cap is a heavy-duty structural connector engineered by Simpson to deliver a higher-capacity column-to-beam connection in new construction or replacement applications. Designed specifically to be welded to the lally column and attach to the girder, this cap features integrated side plates that capture the beam for a safer, more controlled installation process than standard cap plates - making it a reliable choice for contractors and builders working with engineered lumber beams in residential and light commercial framing.

Key Features

• Side plates capture the beam during installation - reduces the risk of misalignment and creates a safer, more controlled connection process compared to standard cap plates
• Cap fits over the column for precise positioning prior to welding - ensures accurate placement before final attachment, saving time and reducing installation error
• 7-1/8 in. seat width provides adequate bearing length for larger girder reactions - supports the higher loads common in engineered lumber applications without compromising structural integrity
• Compatible with 7 in. LVL/PSL/LSL engineered lumber beams and girders - purpose-built for today's most common engineered beam sizes, eliminating the guesswork of fit
• Made from 12-gauge steel with a Simpson Strong-Tie gray paint finish - delivers the structural strength and corrosion resistance needed for long-term performance in demanding framing environments
• Designed specifically for 3-1/2 in. outside diameter lally columns - purpose-matched sizing means no improvised fitment, supporting a code-compliant and structurally sound column-to-beam assembly

Why This Product

• Built for higher-capacity connections - where standard cap plates fall short, this column cap is engineered to handle larger girder reactions, making it well suited for structural upgrades and replacement column projects
• Safer by design - the integrated side plates hold the beam in position during installation, giving installers a more secure and predictable process than conventional cap plate alternatives
• Precision fit for lally column applications - the collar slips over the column before welding, ensuring exact positioning and a cleaner, more professional finished connection
• Trusted Simpson engineering - backed by Simpson's long-standing reputation in structural connectors, this cap is designed to perform in both new builds and demanding replacement scenarios where connection reliability is critical
