To install walers, each waler is loosely placed across a row of
quick-locks at a tilted angle. The wale is then struck with a hammer
to set it firmly into the quick-lock brackets.
A 4 × 4 or double 2 × 4 waler should be used at the top of forms, if
the forms are to be stacked. Strongbacks should be placed every 6 to 8
ft for form rigidity. Panels for subsequent lifts are placed by a worker
on a platform supported by scaffold brackets. These panels can be
attached to the strongback with a strongback clamp.
