Cuplock Scaffolding System – Technical Specifications
1. Cuplock Vertical Standards
Vertical standards form the main load-bearing framework of the Cuplock system.
Each standard is fitted with fixed bottom cups and sliding top cups at regular intervals.
| Length (m) | Outer Diameter | Material Grade | Weight (kg) | Top Cup | Bottom Cup |
|---|---|---|---|---|---|
| 0.5 | 48.3 mm | MS / EN-8 | 2.80 – 3.20 | Fitted | Fitted |
| 1.0 | 48.3 mm | MS / EN-8 | 5.60 – 6.20 | Fitted | Fitted |
| 1.5 | 48.3 mm | MS / EN-8 | 8.40 – 9.20 | Fitted | Fitted |
| 2.0 | 48.3 mm | MS / EN-8 | 11.00 – 12.30 | Fitted | Fitted |
| 2.5 | 48.3 mm | MS / EN-8 | 13.80 – 15.10 | Fitted | Fitted |
| 3.0 | 48.3 mm | MS / EN-8 | 16.50 – 18.00 | Fitted | Fitted |
2. Cuplock Horizontal Ledgers
Horizontal ledgers connect vertical standards and provide lateral stability to the structure.
Forged blade ends ensure secure locking within the cup joint.
| Length (m) | Tube Diameter | Ledger End Type | Material Grade | Weight (kg) |
|---|---|---|---|---|
| 0.6 | 48.3 mm | Forged Blade End | MS / EN-8 | 2.50 – 2.80 |
| 0.9 | 48.3 mm | Forged Blade End | MS / EN-8 | 3.60 – 4.00 |
| 1.2 | 48.3 mm | Forged Blade End | MS / EN-8 | 4.80 – 5.20 |
| 1.5 | 48.3 mm | Forged Blade End | MS / EN-8 | 6.00 – 6.50 |
| 1.8 | 48.3 mm | Forged Blade End | MS / EN-8 | 7.20 – 7.80 |
| 2.0 | 48.3 mm | Forged Blade End | MS / EN-8 | 8.00 – 8.50 |
3. Cuplock Accessories
| Component | Material | Description | Weight |
|---|---|---|---|
| Top Cup | Forged Steel | Locks horizontals | 0.40 – 0.50 kg |
| Bottom Cup | MS / Ductile CI | Fixed node point | 0.25 – 0.35 kg |
| Ledger Blade | Forged Steel | Engages cup joint | 0.25 – 0.30 kg |
| Spigot Pin | Mild Steel | Connects verticals | 0.35 – 0.45 kg |
| Base Jack | Mild Steel | Height adjustment | 3.5 – 4.5 kg |
For slab shuttering and staging work, the cuplock drop head allows adjustable connections and early striking without disturbing the main support structure.
4. Load Capacity of Cuplock Scaffolding System
| Component | Safe Working Load |
|---|---|
| Vertical Standard | 40–50 kN (depends on spacing & height) |
| Ledger | Bracing / support only |
| Cuplock Tower | Safe up to 6–10 meters with bracing |
5. Surface Finish Options
| Finish | Benefits |
|---|---|
| Painted | Economical, corrosion resistance |
| Hot-Dip Galvanized | Long-term & outdoor use |
| Powder Coated | Clean, scratch resistant |

Cuplock Locking Components & Accessories
A key strength of the Cuplock scaffolding system is its locking accessories, especially top cup and bottom cup accessories. These components lock ledgers and transoms securely at every node, ensuring structural stability and safe load transfer.
Contractors rely on these accessories to complete the Cuplock framework efficiently, because they combine with verticals, horizontals, and base jacks for faster erection and repeatable site performance.

Components of the Cuplock Scaffolding System
To build a safe and fully compatible Cuplock structure,
standard verticals are combined with the following components:
- Cuplock Horizontal Ledgers
- Cuplock Intermediate Transoms
- Top Cup & Bottom Cup
- Cuplock Base Jack / Adjustable Jack
- Cuplock Spigot / Joint Pin
- Steel Planks / Scaffold Boards
Because all components follow standard Cuplock specifications, they fit together seamlessly. As a result, contractors achieve faster erection, balanced load distribution and improved site safety.
Frequently Asked Questions (FAQ)
Q1:What is a Cuplock scaffolding system used for?
Cuplock scaffolding systems are used for construction, slab formwork support, industrial access platforms, staging, and infrastructure projects where fast erection and high load performance are required.
Q2:How does the Cuplock locking mechanism work?
The system uses a fixed lower cup welded to the vertical standard and a sliding upper cup. Ledger blades sit inside the lower cup, and the upper cup is hammered down to create a rigid, secure connection.
Q3:What are the main components of a Cuplock system?
A complete setup includes vertical standards, horizontal ledgers, intermediate transoms, top cups, bottom cups, base jacks, spigot pins, braces, and steel planks.
Q4:Is Cuplock scaffolding suitable for heavy slab formwork?
Yes. When properly installed with correct spacing and bracing, Cuplock systems provide strong vertical load capacity and are widely used for slab and beam formwork support.
Q5:Do you supply Cuplock scaffolding systems in bulk?
Yes. AMCO Exports manufactures and supplies complete Cuplock scaffolding systems in bulk for construction projects across India and export markets.
