SPECIAL ROPE WRENCH WARNINGS
RP280 Rope Wrench
Never use as life support. Failure to use proper life support
will lead to serious injury or death.
For use only by arborists who are experienced in SRT. Using
the Rope Wrench without proper training and experience with
SRT can lead to serious injury or death.
Practice using device “low and slow” before using at heights.
Improper orientation of installation will cause the device not
to function.
Read and follow all of these instructions before using the
device.

RP280 series: Issue B - March 2018
The Rope Wrench is meant to be used by arborists servicing, accessing, or maintaining trees in conjunction
with a Single Rope Technique (SRT) conguration. The Rope Wrench is a friction control device that allows
a climber to ascend and descend a single rope without changing equipment. When used as part of a
secure hitch based climbing system, it allows the climber to smoothly control the rate of descent by
adding friction to the climbing system.
The Rope Wrench is NOT:
•a life support device. It is, however, a load- bearing device that may
bear more than 50% of the climbers weight during the climb;
•for use without a life supporting friction hitch or similar device
that will immediately stop descent in an emergency situation;
•for use by persons novice to SRT techniques;
•an SRT training device.
The Rope Wrench has two gears, neutral and engaged, as shown below.
Neutral Gear
(Fig 1a) The climbing rope can pass freely through the Rope Wrench.
Engaged Gear
(Fig 1b) Due to downward loading on the tether attachment point, the climbing rope is bent into an S
shape by the Wheel and the Slic Pin. The climbing rope may still pass through the Rope Wrench, but the
Slic Pin and Wheel apply friction that slows it down.

Rope Wrench
Always use the original Rope Wrench manufactured by ISC. Do not attempt to use a “home-made” Rope
Wrench.
Climbing Rope
It is recommended that a 11mm to 13mm diameter, 16 or 24 strand rope made of nylon, polyester,
polypropylene or kernmantle and that is approved for arboriculture be used with the Rope Wrench
system. Ultra static climbing ropes are not recommended. The rope should have just enough “give” or
“bounce” to be comfortable.
Friction Hitch
It is advised that a heat resistant rope of a different material than the climbing rope be used for the
friction hitch.
It is the responsibility of the climber to select a suitable friction hitch.
(Note 1) The above recommendations for the selection of ropes are general guidelines only. There are
many factors that go into selecting suitable ropes for climbing. A professional arborist should carefully
consider all the factors present before making a decision regarding the ropes to be used.
(Note 2) It is recommended that each rope used in the Rope Wrench system be a different colour or
pattern for clarity of distinction.
Tether
It is required that a stiffened tether be used in conjunction with the Rope Wrench. Stiffened tethers
designed specically for use with the Rope Wrench are commercially available. Do not use tethers made
of a brittle material such as acrylic or wood.
It is the responsibility of the climber to select a suitable tether.
Equipment Requirements
Fig 3
DANGER: FREE FALL HAZARD
Do not use a loose or supple tether with the Rope
Wrench. It may become entangled in the Rope
Wrench and cause it to be locked in neutral and
release the grip of the friction hitch. This will lead
to free fall resulting in serious injuries or death.
Dangerous result of using a loose or supple tether:
Rope Wrench is stuck in neutral position and could
release the grip of the friction hitch below it.
Fig 3
A suitable tether allows 8cm (3") of room between the hitch and the Rope Wrench in an engaged and
fully equalised set up

RP280 series: Issue B - March 2018
It is always recommended that the climber wear a helmet, boots,
and safety glasses at have been commercially manufactured for
arboriculture.
Karabiner
Helmet, Boots and glasses
Harness
The harness selected for use with the Rope Wrench system must
be adjusted to best t the climber’s body. Suspended work
positioning harnesses are recommended for use with the Rope
Wrench system. Harnesses with a chest attachment point may be
used with the Rope Wrench and should be attached to the Tether
Attachment Point or to the tether itself. A chest attachment point
should not be load bearing and is only meant to keep the system
upright and to keep the slack out of the system. (See section titled
Setting Up the Rope Wrench System).
The karabiner selected must be designed for use in arboriculture;
be self-closing;
be self-locking;
take three consecutive and deliberate motions to unlock (triple
locking).
Be large enough to ensure that when congured, no loading or
interference with the gate occurs.
Be secured such that no loading or interference with the gate will
occur.
(The ISC HMS Karabiner is an example of an acceptable Karabiner).

Optional Equipment Recommendations
WARNING: USE OF A FRICTION HITCH
Always remember that the Rope Wrench is not a life support device and even a
system using ascenders in conjunction with the Rope Wrench requires a
properly tied and functioning friction hitch. Failure to do so can result in serious
injuries or death.
Other PPE
Each climb will have its own unique set of obstacles and hazards
that should be well understood before climbing begins. Use of other
PPE such as ear, face, hand, leg and respiratory protection will
depend on the level of exposure of the climber to these hazards.
Slack-Tending Pulley
A pulley is not required, but is recommended to assist in keeping
slack out of the system and moving the friction hitch up the
climbing rope during ascent. Use a pulley designed for climbing
systems, such as the ISC Micro Pulley.
Ascenders
Mechanical ascent devices such as foot or hand ascenders are
compatible with the Rope Wrench. Any time more gear is added to
any rope system it increases the complexity and likelihood of
disorder and entanglement. Extra care must be taken to maintain a
clean and tidy system when using ascenders as becoming entangled
in gear can lead to catastrophe especially when panicked.
Back-up Descent Device
During a particulary long descent, the life of the friction hitch can
be prolonged by incorporating the use of a back-up descent device.
A munter hitch or a gure eight may be used above or below the
friction hitch in place of or in conjunction with the Rope Wrench. A
back-up descent device can also be used if the Rope Wrench
becomes incapacitated during the course of the climb. (e.g., if the
climber loses the Slic Pin).
