Cuplock System Scaffolding

Cuplock is a node-based scaffold system. A forged bottom cup is fixed to the standard at 500 mm intervals. Ledger blades drop into the cup.

How the cup joint locks

Each standard carries a fixed bottom cup at 500 mm spacing. The ledger ends have forged blades. The blade is dropped into the bottom cup.

The top cup slides down over the blade. A hammer strike on the top cup locks the joint. No bolts or wedges are used.

The cup joint is self-centering. It aligns the ledger at the correct level. The connection is rigid under load.

Dismantling is the reverse. The top cup is struck upward. The ledger blade is lifted out of the bottom cup.

Set base jacks	Place base jacks on the ground. Adjust the nuts to a common level.
Place standards	Insert the first standards into the base jacks. Check vertical alignment.
Connect ledgers	Drop ledger blades into the bottom cups. Slide top cups down and strike.
Add diagonal braces	Fit diagonal braces to the cups. Strike the top cups to lock.
Install platforms	Lay steel planks on the ledgers. Secure the planks against uplift.
Repeat upward	Add the next lift of standards. Repeat the ledger and brace sequence.

Cuplock components are available hot-dip galvanized or painted. Hot-dip galvanizing is the standard finish.

Galvanized cuplock resists corrosion. It has a service life of 15 years or more. Painted cuplock is a lower-cost option for dry climates.

Painted finish is available in red, orange, blue, or yellow. The paint is applied after welding. The cup joint works the same in both finishes.

Grid, clear height and quantities are enough. We return dimension sheets and load data for your case.
