Diagonal bracing
Scaffold tubes with Ø
48.3 x 4.05 mm, bolt-on couplers
48/M14 and swivel-joint couplers
48/48 are needed to build the
diagonal bracing required.
A horizontal tube is required
for STB 300 (Fig. 13.1) and
STB 300 plus (Fig. 13.2).
The STB 450 requires two hori-
zontal and one diagonal scaffold
tube (Fig. 13.3).
If height extensions are used,
additional horizontal scaffold
tubes must be installed from the
second height extension upwards
(Figures 13.4 and 13.5).
