Festool MFS Fence System Instruction Manual page 5

What is the Festool
MFS fence or guide
system?
At it's heart, the MFS is a very
precise, complex aluminum extru-
sion 80mm wide and 16mm thick.
It comes in 200mm, 400mm,
700mm, 1000mm and 2000mm
lengths shown in this photo sitting
on top of a Festool guide rail.
That is roughly 3 1/8" wide, 5/8"
thick with standard lengths of a bit
over 8", a bit over 16", 27 1/2", 39
3/8" and 78 3/4". From here on I
will only refer to the metric sizes as that is
Special MFS "V" track, one
on each side and three on
each face
how each of these extrusions is identified
and marked.
Along one edge are ruled marks in milli-
meters starting at zero and going to the
length of the extrusion. The ends are cut
very accurately at 90 degrees.
On the top and bottom 80mm widths are
"T" tracks the same size and shape as
5
the Festool guide rail "T" tracks so the
Standard Festool "T"
track on each face
same Festool clamps and other
accessories will fit.
On both sides of the 80mm
widths and along each 16mm
side are "V" shaped tracks
unique to the MFS. Festool
supplies a variety of different
nuts that slide into these "V"
tracks to allow the attachment
of different supplied and shop
built components.
One of the nuts that fits into the
track on one or both 16mm
sides is a threaded insert
(shown below) which is held
firmly in place. A hole through
that insert allows a 4mm cap
