Samson Professional

For well over 100 years, Samson has been the leader in

developing and manufacturing braided ropes. During

the 1800’s, Samson perfected the unique concept of

incorporating reinforcement cores within braids to

significantly enhance product performance. In 1957,

the engineers at Samson took this innovation another

step forward and developed the modern synthetic

double braid. By combining newly developed fibers in

their patented construction, ropes could be engineered

with those characteristics critical to the applications for

which they were designed. Performance factors, such as

strength, elongation, flexibility, and abrasion resistance,

could now be engineered into the rope.

With this heritage, it’s easy to see why Samson ropes excel in

workplaces as tough as those encountered by the professional

arborist. Samson’s line of tree ropes are specifically engineered

to maximize performance where ropes are expected to run

against bark and through crotches, support and control

descending loads while providing a reasonable working life and

margin of security for climbers working in the tree.

The most complete line of products in the industry...Samson’s

line of Arborist ropes includes both climbing and rigging ropes,

12 and 16 strand braided constructions, double braided, and

three strand twisted ropes. Each construction and combination

of fibers offers its own mix of performance characteristics.

Strength, elongation, abrasion resistance, and snag resistance

are all factors to consider in choosing the appropriate line for

a given task.

This catalog has been designed as a complete reference on

Samson Arborist products. In it you will find specifications for

each product, which allows comparison between products to

ensure that the product chosen will function in its role in the

workplace. In addition, we have included reference materials on

usage and inspection techniques for ropes in general.

In order to promote safety on the job site, and ensure that our

products are used most effectively, Samson has teamed up with

the arborist community to promote and provide current

information on effective and safe climbing techniques.

Please refer to our special sections on Climbing Knots; Knots

and Rigging; Slings; Standards for Strength and Usage and

Rope Inspection and Retirement. While not intended to be

a comprehensive guide to this demanding aspect of the

arborist’s profession, it will introduce a few basic concepts,

and hopefully encourage the search for more information

on this critical aspect of the arborist’s occupation.

Samson Climbing Lines

Samson has been in the cordage industry

since 1884. During our many years of

operation, we have responded to many

requests for specialized products for new

or unusual applications that require

strength members built to specified

characteristics such as strength, stretch,

hand/knotting features or weight. Projects

have ranged from developing a space

capsule retrieval line, deep water lift lines

to retrieve a Russian submarine, power

company winch and pulling lines, and

Arborist climbing lines.

As with all industrial applications,

specialized needs and preferences are

generated to meet these requirements,

and a constant product development

program is always underway at Samson.

To meet the demand for a higher

strength, lower stretch climbing

line that would allow good visual

recognition, True-Blue was developed.

Traditional preferences continued for

a 3-strand with low stretch, higher

strength and better service life than

manila. To service these requirements

Tree-Master was created. Today, the

continuing growth of the “Footlock”

climbing technique has required the

development of a braided rope

construction that would have maximum

flexibility while maintaining a firm

round shape during operation; plus,

be a high visibility rope and fully

identifiable from all rigging lines.

In the early 1970’s we were asked to

develop a synthetic line to replace manila

climbing lines. The project was accepted

and we worked with universities,

distributors and arborists. After fourteen

months and seven design evaluations,

Arbor-Plex was created and released as

the first significant braided rope as a

climbing line for the Arborist Industry.

Our latest innovation comes from

working closely with ArborMaster®

Training to create the ultimate climbing

line: ArborMaster®. Several years of

research and development went into

creating this product to meet the

demanding requirements of today’s

professional climbers.

ArborMaster ®

premium 16-strand braided polyester

construction. With a uniquely stabilized

nylon core.

Samson is committed to constantly

meeting the challenges of the Arborist

Industry and assuring the highest

consistent quality climbing lines

available. We are ISO 9001 certified

and our climbing lines meet or exceed

ANSI Standard Z133.11-2000.

Important Note About

Climbing Lines for

Lowering Operations:

Climbing lines should not be used as

lowering lines, come-along ropes or bull

ropes. These constructions are designed for

maximum flexibility and excellent handling

qualities when used in climbing applica-

tions. These design characteristics are not

necessarily suitable with lowering

operations. This is especially important

if the rope has already been retired from

climbing service. Other types of ropes

specifically designed for lowering and

come-along operations should be used

for these types of applications.

True-Blue ™

12-strand braided 100% polyester

construction. Each strand consists of

blue fiber plied over white fiber to assist

detection of cover wear.

It is our commitment to product

development, compliance to industry

standards and constant innovation

that keeps us ahead of our competition.

Samson Rigging Lines

Rigging is the use of ropes and other

equipment to take down trees or remove

limbs when free-falling is not advisable.

Rigging is the most advanced aspect of

tree work. Even for veteran arborists,

it is best to practice new techniques in

open areas where the risk of accidents

can be controlled and personal safety can

be ensured.

offered with a urethane coating for

maximum toughness, is spliceable using

standard double braid procedures. It is

designed to be used with false crotch

blocks and other rigging hardware so

you can take full advantage of its strength

and durability.

Pro-Master ™

A firm three-strand rope construction

offering reliability as well as economy. It

holds its shape even under heavy use and the

spun fiber on the surface offers excellent grip

and knot holding. Identified by a green ID.

For price and performance there isn’t a better

three-strand rigging rope in the marketplace.

Arbor-Plex ™

A torque balanced rigging rope available

in 5/8’’ and 3/4’. It is a twelve-strand

tightly braided construction with excellent

wear resistance, high strength and light

weight. Each strand has a core of

polyolefin wrapped with polyester in a

DuraTite construction process which

makes it unspliceable. First offered to the

industry in the mid 1970’s as a rigging

line, it is widely known and trusted as a

“work horse” for virtually all rigging uses.

The techniques and tools will vary with

each job site and an experienced worker

will take advantage of the many new blocks

and lowering devices to safely and

efficiently lower tree sections. Advances in

rope construction, as well as new and

better synthetic fibers, are making the job

of rigging easier and safer and the

importance of using reliable rigging ropes

cannot be overstated. Samson offers

several types of rigging lines designed

specifically for the Arborist industry.

Samson’s rigging ropes offer the best

combination of strength, wear resistance

and elongation while taking some of the

mystery out of choosing the right rope.

STABLE BRAID ™

2-in-1 ® double braid construction

consisting of a braided polyester

cover over a braided polyester core.

Tenex ™

Tenex is a firm, round braided construction

offering high strength, low stretch and

outstanding abrasion resistance. The

proprietary coating enhances the rope’s

firmness and resistance to abrasion and

snagging. These characteristics make

Tenex an excellent choice for rigging

line and for slings.

Static Rope ™

A kernmantle rope construction that can

be used for specialty rigging requirements.

Possesses excellent shock mitagation and

firm round shape under load.

TENEX ™

Twelve-Strand construction of high tenacity

polyester with Samthane coating.

most widely used as a lifting line or

winchline in many industries where higher

strength and durability along with easy

handling are needed in a relatively small

diameter. It is available in sizes from

1/2’’ to 7/8’’, with other sizes available by

special order. Introduced to the arborist

industry in 1993 as a rigging line, this
