|---|---|---|
| 2 | 6.14 × 4 m: 41 | 6 × 4 m: 34 |
| 4 | 12.28 × 6 m: 99 | 12 × 6 m: 85 |
| 6 | 18.42 × 8 m: 170 | 18 × 8 m: 154 |
| 8 | 24.56 × 10 m: 279 | 24 × 10 m: 251 |
| 10 | 30.7 × 12 m: 390 | 30 × 12 m: 346 |
How to choose between them
- Use the system you own or can rent nearby: a mixed yard costs more than a few extra pieces.
- Check the bay lengths against your facades: more bay lengths fit odd lengths more closely.
- Compare the depths: a deeper scaffold gives more room to work but uses different decks and transoms.
- Count the pieces to handle, not only the price per piece: more pieces mean more transport and erection time.
- Follow the manufacturer’s instructions and approval for ties and loads; ScaFix plans, it does not approve.
