Cuplock scaffolding is a modular system scaffold widely used in construction, infrastructure, and industrial projects. It adopts a unique cup-and-lock joint connection, which allows quick fastening of ledgers and braces to the vertical standards without the need for bolts or loose fittings. This simple locking mechanism ensures fast installation, high strength, and excellent stability.
The system is designed with standardized modular components including verticals, ledgers, diagonal braces, base jacks, U-head jacks, steel planks, guardrails, and toe boards. The 500mm interval cup joints on the standards provide flexible height adjustment and versatile combinations for different structures.
