FORK-SUPPORT FOR 617
The fork has two functions:
• it prevents the beam, when closing, from bending and splitting
if its end is stressed by extraneous forces.
• it allows the beam to rest when closed and thus prevents the
profile bending downward.

POSITIONING THE FORK-SUPPORT FOUNDATION PLATE FOR 617
To position the fork-support foundation plate, refer to fig.23 where:
L = beam length (in mm)
A = L - 500 (in mm)
N.B.: For correct alignment, we advise you to position the fork-
support after fully installing the beam - in this way, the beam
will be correctly positioned at the centre of the fork.
Upright
All values in mm
