One joint, no loose parts
Cuplock has no bolts, wedges or clips to lose on site. Every joint is a fixed bottom cup and a sliding top cup on the standard.

Cuplock System
Cuplock scaffolding and shoring: 60 mm standards with a cup joint every 500 mm, ledgers with forged blades, base jacks and U-head jacks. One hammer blow locks up to 4 ledgers at a joint.
Built to your size
Bay size, lift height and finish are made to your order.
Cup spacing, standard and ledger lengths and jack lengths can all be changed. The model shows 2 bays of 1.5 m by 1.5 m: one decked for access, one shoring a pair of lattice beams on U-head jacks.

Bottom cup and top cup
A bottom cup is welded to the standard every 500 mm. The top cup slides down over the ledger blades and turns against a lug. One hammer blow tightens it.
- Spacing: 500 mm, or to order
- Ledgers per joint: Up to 4

Base jacks
A threaded stem on a base plate under each standard levels the scaffold on uneven ground.
- Load capacity: Up to 4 T
- Hollow jack lengths: 230, 350, 450, 600 mm
- Solid jack lengths: 300, 350, 450, 600 mm

U-head jacks
For shoring, a U-head jack on top of each standard holds a pair of lattice beams and adjusts their height.
- Adjustment: 300 to 600 mm
- Load capacity: Up to 4 T

Diagonal braces
A swivel-coupled diagonal on the face of each bay keeps the scaffold square.

Deck, hooks and toe guards
Anti-slip steel planks hook over the ledgers. Toe guards 150 mm high run along the deck edge, and 2 ledgers above the deck act as guard rails.
