des, a sub-unit of the fall-protection system. For each stopfor
model exists a particular type of anchor line, specially designed
for that stopfor model.
Each stopfor model, in association with the relevant anchor line,
has undergone an EC-type examination carried out by a notified
body.
Using a stopfor on a non-adapted anchor line for that model,
as provided for in this instruction manual, could prevent the
device from functioning, thus putting the user's life at grave
risk when not preventing a fall.

• The stopfor S travels along a stranded anchor line, by accom-
panying the user without necessitating any manual involvement
during its journey up or down, and automatically blocks on the
rope in the event of a fall.
• The stopfor P is identical to the stopfor S, but is dependent
upon the anchor line.
• The stopfor A works in the same manner as the stopfor S, but
has an additional safety device, the "anti-panic device". Such
device stops a fall, even if the user fails to let go of the control
lever.
• The stopfor K has the same function as the stopfor A. It is
installed on the halyard and does not use the same blocking
principle.
• The stopfor B is the equivalent of the K model, except that it is
installed on stranded rope.
• The stopfor AP is a variant of the stopfor A to which a manual
blocking function has been added. Such function enables the
user to block his stopfor on the rope.
The fall protection system consists of the components described
below.

The stopfor can only be used with anchor lines certified exclusi-
vely by TRACTEL S.A.S.
stopfor A, S, AP and P:
The anchor line is a stranded polyamide 14 mm diameter rope.
It is supplied in multiples of 10 m in length.
stopfor K:
The anchor line is a static polyamide halyard, the diameter of
which is between 10.5 and 12.5 mm.
Each anchor line (either rope or halyard) is equipped with a buc-
kle at one end to fix the rope to the anchoring point. At the other
end, a machined tip prevents the stopfor from being accidentally
released from the anchor line.
The anchor line's breaking resistance is above 22 kN.
The anchor line should be exclusively used as a safety line when
working at heights to enable access to the work place in full secu-
rity.
stopfor B
The anchor line is a 12 or 14 mm diameter stranded polyamide
rope.

• stopfor S (page 2)
By way of a lanyard, the user is attached to the jaw (I), the control
lever (K) and the clevis mounting (J), all interdependent. The
stopfor S moves automatically along the anchor line. Due to a
slight tension (equivalent to the device's weight), transmitted to
the user via the lanyard, the jaw is opened and the stopfor S can
move along.
The casing is equipped with hinges to enable opening for instal-
ling the anchor line inside the stopfor S. The casing is closed by
screwing a knurled knob (E) and a threaded spare part found on

the side of the removable flap (F) into a crimped nut on the
casing. Two simultaneous actions are necessary to open the
casing: pushing the bolt (D) to unlock and unscrewing the knur-
led knob (E). The anchor line now vertically positioned (30° maxi-
mum authorised angle with the vertical), fastened at its upper
limit and hanging naturally prior to the stopfor S set-up (page 2),
the guide pin (N) of the stopfor S only authorises closure of the
device on the positioned anchor line if the device is presented
with the arrow engraved on the casing pointing upwards. The rol-
ler (M) guides the anchor
Should the user fall, the lever will swing over by 45° due to the
force applied by the lanyard, and the rope will be blocked against
the removable flap (F) by the jaw.
• stopfor A (page 2)
The stopfor A has two independent release systems which ena-
ble the jaw to engage on the anchor line and then to gently stop
the fall. The first system is equivalent to that of the stopfor S, with
the user making the control lever swing over during his/her fall.
The second system is equipped with an "anti-panic" device, whe-
reby the roller detects any increase in speed caused by the lever
being held inadvertently open during a fall and then drives the
jaw towards the closed position.
• stopfor AP equipped with a blocking device (page 2)
Pressing the lever (H) simultaneously upwards and to the right
enables it to come up flush with the release lever (G). Such lever
holds the jaw tight against the anchor line, thus preventing any
movement of the device on the anchor line. The release lever
can be deliberately unblocked by the user.
• stopfor K / stopfor B (page 2)
The stopfor K / stopfor B moves freely along the anchor line. In
the event of a fall, the device swings over, thereby bringing the
anchor line into contact with the shaft's upper part. The shaft
revolves inside the device and then grips the anchor line.
The system is comprised of two flanges articulated around the
camshaft (Q). The device is opened by pivoting the mobile flange
(R). The pressure of the shaft is maintained on the anchor line
by the shaft's spring (S). As soon as the anchor line is in posi-
tion and the connector has locked the two flanges, it is no longer
possible to open the device; the anchor line is thus imprisoned
inside.The jaw (j) is firmly attached to the control lever (l) and the
eye (k) to which the user is attached via a lanyard. The stopfor S
moves automatically along the rope. A slight tension, equivalent
to the weight of the device, is transmitted to the user via the
lanyard, allowing the jaw to open and the stopfor S to move.
The housing, which is hinged, opens to allow the rope to be
inserted in the stopfor S. The housing is closed using a knurled
button (f) and a threaded part on the moveable flap side (g).
