Top Cup (3 & 4 Lugs) – Secure Locking for Cuplock Scaffolding

VRS International is a reliable manufacturer and exporter of Top Cups (3-lug and 4-lug) for Cuplock scaffolding systems. These components are essential for locking the horizontal ledger blades to the vertical standards, ensuring fast and secure connections.

Top cups are typically cast or forged and designed with 3 or 4 internal lugs to engage with ledger blade slots. When rotated down over the ledger blade, the lugs grip the blade securely against the bottom cup, forming a strong joint.

Our top cups are made from ductile cast iron or steel, heat-treated for added strength and durability. Available in 3-lug and 4-lug versions, they suit standard 48.3 mm OD Cuplock systems and comply with BS 1139 / EN 12810 specifications.

The Top Cup with 3 or 4 lugs is a vital component of Cuplock scaffolding systems, used to lock ledger blades firmly onto vertical standards. Designed for quick assembly and strong grip, it ensures rigid, safe scaffolding structures on construction sites.
