Why Contractors Choose Cuplock Scaffolding for Heavy Loads

Cuplock scaffolding, also called cup lock or cup scaffolding, is a straightforward modular system built around a unique 4-way blade-and-cup locking node. ACE SCAFFOLD Cuplock is a favorite for shoring and access where loads are high and repetition is constant.

Fast, foolproof locking

Each standard carries fixed bottom cups and sliding top cups. Drop the ledger blades into the bottom cup, slide the top cup down and tap it tight with a mallet, with no loose wedges and no small parts to lose. A single node locks up to four ledgers at once, so decks go up quickly and square.

Heavy-duty by design

Cuplock standards and ledgers use high-strength galvanized steel and carry substantial vertical and horizontal loads, which makes the system ideal for slab shoring, bridge decks and high-rise access. The same components double as formwork support with drop heads and infill beams.

One system, many jobs

From a simple access tower to a multi-bay shoring grid, Cuplock scales without special connectors. ACE SCAFFOLD ships complete Cuplock kits with planks, braces and transoms, and offers OEM/ODM to client dimensions.
