Bil-Jax Ring Lock compared with similar systems on the same house
The same example house, computed by the same engine with each system's bay length and default depth. The difference in piece count comes from the bay length, the depth and how the system is built.
| System | Bays on the long wall | Depth | Parts in all |
|---|---|---|---|
| Bil-Jax Ring Lock | 1 × 0.91 m + 3 × 3.05 m + 1 × 2.44 m | 0.73 m | 533 |
| BrandSafway SafLock | 1 × 1.15 m + 2 × 3.05 m + 1 × 2.13 m + 2 × 1.57 m | 1.15 m | 665 |
| Waco Frame | 1 × 3.05 m + 4 × 2.13 m + 1 × 1.52 m | 1.52 m | 368 |
How to compare the setup
- These are fixed ScaFix examples, not customer jobs. Use the wall dimensions and roof shape stated with each example.
- Compare the same system variant, bay lengths, scaffold depth, deck heights and access. Matching house dimensions alone do not give matching parts lists.
- The displayed quantities are calculated by ScaFix's engine. Check the setup against the manufacturer's assembly instructions and the actual job; a parts list is not a structural calculation.
Limits
- The number of wall ties follows the system's tie rule. Their positions must be checked against the manufacturer's assembly instructions.
- Round corners, silos and hanging scaffolds are in Pro. A round scaffold is not a standard configuration and needs a calculation or the supplier's documentation. A hanging scaffold (Layher Allround and HAKI Universal) always needs a structural calculation from the supplier or an engineer.
