Special Thanks to Arborone tree service.
The Tendril is Sterling Rope’s first arbor-specific climbing line. We developed this
new double braid with the input and feedback of field arborists. They asked for
a smooth handling, all-conditions climbing line with low elongation. We wanted
to deliver the best combination of features in a rope that meets CE and ANSI
certifications. Refreshingly, everyone got what they wanted. For more information
about the Tendril, see page 3.
The Atlas is the perfect complement to our Tendril: a tough, burly rigging line
with great knotability and the ability to tackle your biggest haul jobs. Built on our
heritage of creating superior dynamic ropes, the Atlas can absorb large shock
loads and continue to perform flawlessly. Learn more about the Atlas on page 4.
The BARC is our Chain Reactor re-imagined as an oversized Rigging Chain. Built
using 1” T9800 webbing, the BARC functions as a basal anchor, a sidekick for our
Atlas, or any number of other rigging duties. So what does BARC stand for? Turn
to page 11 to find out.
RIT multisling prusik
The Swiss Army would be proud of this simple, yet versatile innovation for
Arborists. Is it a footloop? An anchor point? A redirect? In a word: yes. To find
out more about what it can do, turn to page 9.
Introducing Sterling Rope’s new Tendril Climbing line. Designed from the ground up to
meet the specific needs of Arborists, the Tendril is built to perform consistently in wet and
dry conditions with low elongation and balanced handling. Constructed with a softer feel,
the 11.6mm Tendril is easy to grip with or without gloves. It’s less stiff than traditional static
ropes and runs smoothly with friction hitches or mechanical devices. Great as a work
positioning line as well as an access line, the Tendril resists flattening or glazing even under
heavy use. Spliceable, or available with a sewn eye termination. Meets EN 1891 Type A
and ANSI Z133 requirements.
Designed with rigors of tree work in mind, the Tech11 is an 11mm rope constructed with a
Technora® sheath and nylon core. This rope was rated the most durable climbing line by
our field testers and works well in DdRT and SRT systems. It has been exposed to some of
the roughest conditions by rope access, fire rescue and arboriculture professionals. Proven
to be extremely tough, it will handle the most extreme conditions, and keep working long
after other ropes would be retired.
htp 3/8”(10mm) & 7/16”(11mm)
HTP is a high tenacity polyester rope with low stretch properties and high moisture
resistance. The benefits of using HTP include superior durability, better UV resistance than
nylon and aramids, and just the right amount of stiffness for improved SRT work. The 3/8”
(10mm) and 7/16”(11mm) are great for ascension and rappeling due to its high efficiency.
3/8” (10mm)colors 7/16” (11mm)colors
safetypro 7/16” (11mm)
The workhorse of the SafetyPro series, the 11mm offers a smooth tight sheath that allows
the rope to run smoothly through gear. A technical work and rescue line, manufactured to
meet the EN 1891, Type A standard, and also passes the ANSI Z133.
Introducing Sterling Rope’s new Atlas
Rigging line. When you are removing trunk
sections, your rigging system needs to
be able to absorb large dynamic forces.
That was the design mission behind our
Atlas Rigging line. At Sterling, we’ve been
engineering ropes to handle high kinetic
energy loads for over two decades. Our
9/16”(13.5mm) polyester sheath, nylon
core construction offers a soft hand and
easy knotability even on the burliest rigging
jobs. Designed to work seamlessly with a
Portawrap, capstan winch or rigging blocks,
the Atlas delivers unmatched compatibility
along with strength and durability. The Atlas
is not spliceable, but can be ordered with a
sewn eye termination for knotless rigging.
Sterling Rope has been offering sewn
eye terminations on its ropes for over 14
years. Sterling’s computerized sewing
program makes sewn ends that are stronger
than knots and eliminates the need for
tying them. In addition, carabiners and
connecting hardware can be detached
more quickly from a sewn eye, especially
if under load. We offer optional sewn eye
terminations on all arbor climbing and
rigging lines, and they are the standard
termination on all fliplines and lanyards.
Sewn eyes are available with optional
thimbles upon request.
htp 1/2”(12.5mm) & 5/8”(16mm)
Need a low-stretch rope with a tight sheath
for tree pulling or big haul jobs? The 1/2”
or 5/8” HTP is your rigging answer. Perfect
for all types of technical rope work, rigging
or hauling, the High Tenacity Polyester
ropes are extremely low stretch and feature
UV and moisture resistance.
1/2” colors 5/8” colors
superstatic2 (7/16” & 1/2”)
While it is hard to improve upon a good
thing, twenty years of designing and
building technical ropes taught us how to do
just that. The Superstatic2 7/16”(11.0mm)
and 1/2”(12.5mm) features an all new core
and sheath construction providing smaller,
true diameters for better knotting and gear
lanyards and fliplines
The UP Lanyard is designed to function as
a true work positioning system. Multiple
work and connection options allow for twoin-one
positioning, one handed operation of
tending slack, “M” system configuration or
as a single leg up off a bridge. Built around
our TriTech flipline (see page 6) TriTech
features our most durable Technora®
sheath over a unique inner Dyneema®
jacket covering a nylon core. These fibers
combine to provide a rope lanyard that
protects you against accidental nicks that
could seriously compromise any other rope
lanyard. TriTech offers the best abrasion
resistance and nonconductive properties.
The Ultimate Positioning Lanyard is
available in both 10ft and 12ft lengths.

We guarantee our ropes to be free of defects, under normal
wear and tear and proper use. Ropes, however, do not last
forever. Climbing and technical rope work exposes ropes
to abrasion, fatigue, sunlight, and constant loading. Severe
falls, lack of protection over an edge, exposure to excessive
temperatures, chemicals or improper use will shorten the life
span of any rope. These scenarios, while unusual, point to
the importance of checking and protecting your rope. Sterling
reserves the right to inspect your rope before replacing it or
refunding your money. Sterling is committed to supporting you
to enhance your overall experience with each Sterling product.
This dedication to excellence has awarded Sterling Rope the
highest rating in customer service.
