- 1.52 m lifts; ties every 4 m vertically, every 3.05 m (1 × 3.05 m) / 4.88 m (2 × 2.44 m) / 4.27 m (2 × 2.13 m) along the wall; diagonals at least one per 1 bays in every lift
Wall-tie spacing along the wall for Metaltech Saferstack Mason
ScaFix ties Metaltech Saferstack Mason every 4 m in height. Along the wall a tie sits on a standard, so the spacing is always a whole number of bays: for a wall built from one bay length, the table shows how many bays lie between two tied standards and the spacing that gives. Rule: Metaltech «Exterior Scaffolding Guidelines» (2021) p. 1–2: tie when the height exceeds 3 × the base (24" narrowest frame: 1.83 m), then every 20 ft high and 30 ft along. ScaFix is a planning tool, not a structural approval.
| Bay length | Bays between ties | Tie spacing along the wall |
|---|---|---|
| 3.05 m | 1 | 3.05 m |
| 2.44 m | 2 | 4.88 m |
| 2.13 m | 2 | 4.27 m |
