new products


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.


climbing lines



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.


igging lines



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.

sewn eyes

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

Big Ass Rigging Chain. That’s what our field

testers dubbed it. Actually, BARC stands

for “Basal Anchor Rigging Chain,” but

who are we to argue? Try one and you’ll

be a believer. Building on the popularity

of Sterling’s versatile Chain Reactors

(see below), the BARC is made from 1”

T9800 nylon webbing sewn into individual

full-strength loops for an adjustable and

incredibly strong chain. Designed for use

as a basal anchor with your Portawrap or

other friction brake lowering device, the

BARC can also accommodate your rigging

block aloft. BARC comes in 5ft and 8.5ft

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.
