Function and description

The Stopfor™ is a fall-prevention self-tightening mechanical
device, which comprises, with the flexible anchor line on which
it slides, 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.
DANGER
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 userʼs
life at grave risk when not preventing a fall.
• The Stopfor™ S travels along a stranded anchor line, by
accompanying 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™ M is a Stopfor™ S equipped with a reinforced
spring ensuring permanent locking of the Stopfor™ on the rope.
With the device locked on the rope, the user is required to
manually move the Stopfor™ when descending.
• 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 moves along the length of a guy rope type
belay support and ensures the same function as the
Stopfor™ A. It is installed on the halyard and does not use the
same blocking principle.
• The Stopfor™ KS is a Stopfor™ K equipped with an anti-
turnover system.
• The Stopfor™ KM is a Stopfor™ K equipped with a reinforced
spring ensuring permanent locking of Stopfor™ on the rope.
With the Stopfor™ locked in this way, the user is required to
manually move the Stopfor™ when descending.
• The Stopfor™ KSM is a Stopfor™ K equipped with an anti-
turnover system and a reinforced spring.
• The Stopfor™ B moves along a twisted strand belay rope and
ensures the same function as the Stopfor™ K.
• The Stopfor™ BS is a Stopfor™ B equipped with an anti-
turnover system.
• The Stopfor™ BM is a Stopfor™ B equipped with a reinforced
spring ensuring permanent locking of the Stopfor™ on the rope.
With the Stopfor™ locked in this way, the user is required to
manually move the Stopfor™ when descending.
• The Stopfor™ BSM is a Stopfor™ B equipped with an anti-
turnover system and a reinforced spring.
• 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
® .
exclusively by Tractel
• Stopfor™ A, S, M, AM, 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, KS, KM, KSM
The anchor line is a static polyamide halyard Tractel, the diameter
is 11 mm or 12.5 mm.
• Stopfor™ B, BS, BM, BSM
The anchor line is a 12 or 14 mm diameter stranded polyamide
rope.
Each anchor line (either rope or halyard) is equipped with a
buckle 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 lineʼs 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
security.
3. The Stopfor™
• Stopfor™ S (Fig. 6, 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 deviceʼs 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
installing 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 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 knurled knob (E). The anchor line now vertically positioned
(30° maximum authorised angle with the vertical), fastened at its
upper limit and hanging naturally prior to the Stopfor™ S set-up,
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 roller (M) guides the anchor line into the device.
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.
• The Stopfor™ M (Fig. 6, page 2).
The Stopfor™ M is identical to the specification for the
Stopfor™ S; it is equipped with a reinforced spring ensuring
permanent locking of the Stopfor™ on the rope. With the device
locked on the rope, the user is required to manually move the
Stopfor™ when descending. For user comfort, the Stopfor™ lever
arm is equipped with a plastic grip handle.
• The Stopfor™ A (Fig. 6, page 2).
The Stopfor™ A has two independent release systems which
enable 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,
whereby 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.
• The Stopfor™ AP equipped with a blocking device
(Fig. 6, 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
