The Formwork Experts
Multi-purpose walings SL-1 WU16
● Waling lengths from 0.625 m to 3.00 m
● 20 mm diam. hole-grid (of the WS 10), to permit
utilisation with Top 50 components
● 32 mm diam. hole-grid for connecting the Spin-
dle struts SL-1 T16, and for flexurally rigid joints.
● Higher permitted loads, permitting greater influ-
ence widths
The two different integrated hole-grids make it pos-
sible to use a range of different connection meth-
ods, ensuring suitability for both cut-and-cover and
underground tunnel construction situations.
Permitted internal forces: Multipurpose walings
SL-1 WU16 (without proof of stability – e.g.: buck-
ling)
Practical examples
Connection for Spindle struts SL-1 T16 in the

Note:
Allowance must be made for the welded-in spacer
bolts when fitting connecting plates.
Connected to a spindle or strut along the continu-
ous 20 mm diam. hole-grid.
Connected to bracing tubes by screw-on couplers
