Stripping Corners - Retract and Reset Tool

Stripping:

Turning the hexagonal nut with
an impact wrench (Fig. 25.1), a
ratchet (Fig. 25.2) or a wrench
moves the stripping mechanism
upwards.

This activates the stripping corner
and separates the shaft formwork
from the concrete walls (Fig. 25.3
and Fig. 25.4).
