Wall-tie spacing along the wall for WACO RED Box Frame

ScaFix ties WACO RED Box Frame 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: Waco RED frame scaffolding brochure ORN1701 (BrandSafway 2020) p. 20 «Scaffolding Safety Guidelines» F (SSFI): first tie at 4 × the minimum base, vertical ≤ 26 ft (7.9 m), at each end and ≤ 30 ft (9.1 m) along. ScaFix is a planning tool, not a structural approval.
