Arbor 2016 | Climbing Lines
Our climbing lines are designed from the ground up to meet the specific needs of arborists. Extremely durable and offered in ideal diameters for a wide range of applications, the family of climbing lines work in most climbing/access systems, such as Stationary Rope Technique (SRT) and Moving Rope Technique (DdRT). Sterling’s climbing lines are available with sewn terminations.

Scion™
11.5 mm
Our newest, fully certified addition to the climbing line roster, the Scion Climbing Line’s burly construction and ability to absorb dynamic forces makes this rope ideal for Doubled Rope Technique (DdRT) and Single Rope Technique (SRT). Based off the construction of the popular Tendril, the 11.5 mm Scion has a polyester 24-strand cover and double-braided construction, engineered to have decreased elongation, soft handling and easy knotability. This rope has a tight, durable sheath that can handle mechanical devices and hardware. The Scion is hand spliceable and available with sewn terminations.

Quality components are the backbone of any kit or system, and Sterling has been making the best for over 20 years. However, simply having good pieces is not enough, they need to be thoughtfully integrated together to ensure that they function as a complete package. That’s why our in-house experts devote so much time to selecting what goes into each of our packages and our cadre of professional field testers put each kit and system through its paces. Before we release a new kit or system for use in real-world arbor situations, each has been used, abused, refined and tested until it’s the best it can be.

Arbor Hitch Testing Summary
Sterling conducted a series of static and dynamic tests of popular hitches commonly used in the arbor industry. The purpose of the testing was to provide comparative data for the arbor community on hitch performance. The data presented is for educational purposes only and is not a guarantee of performance. All tests were conducted with new products. The data concludes that different hitches on different ropes provide different results so it is important to ensure components in a climbing system are compatible. Note: 1 kN is equal to 224.8 lbs.
Static Pull Tests This test procedure is a modified version of ANSI Z359.3 Slow Pull Test for Rope Adjusters. We created a test program that will set the hitch at 0.98 kN (approximate load for body weight), reduce the load to approximately 0.0 kN and then ramp to 4.45 kN. We then measured the slippage. Dynamic Drop Test These tests were conducted using a test mass of 100 kg. A fall factor 0.3 was used, which is the free fall distance divided by the length of the rope in the system. The hitch is tied to the host rope and then anchored to the test mass. The hitch is set prior to drop test. The mass is then raised to the prescribed drop height and released. For more information on hitches tested as well as expanded details on the tests performed, please go to sterlingrope.com.

Certifications It’s important to purchase your life-safety equipment from respected and certified manufacturers. Part of understanding this significance is knowing whether products are certified, what the certifications mean and how they are applied to each product. As an ISO 9001 Company, Sterling is proud to offer products that are 3rd party tested and meet CE, NFPA, and/or ANSI Standards on life safety equipment. • CE EN 1891 Type A certifies personal protective equipment for the prevention of falls from a height; specifically low-stretch kernmantle ropes for climbing/access lines. Manufacturing to the CE standard ensures products meet certain quality criteria for climbing and work positioning. • ANSI Z133 is the American National Standard for Arboricultural Operations Safety Requirements. Compliance for this standard is voluntary, but the intent of the standard is to guide arborists in safe work habits. • NFPA 1983 is the National Fire Protection Association’s “Standard for Life-Safety Rope and Equipment for Emergency Service.” This standard requires that a manufacturer is certified to ISO 9001 and specifies performance, labeling, user instruction and test method criteria for rope, connectors, descent devices, anchors and systems. Though not directly related to arboriculture activity, third party testing and certification of our product to this standard ensure that our manufacturing and quality control processes deliver products and systems that work well in technical rope and life-safety applications.
Sterling Rope is a certified ISO 9001 company.
Sterling Rope is a certified ISO 9001 company and all of our certified products must pass third-party testing to the standards we identify. Sterling also maintains a rigorous in house testing program. All minimum break strength (MBS) numbers listed here are from a 3-Sigma MBS test results or are listed at the corresponding standard’s minimum requirement. A 3-sigma MBS is based on a statistical analysis of the breaking strengths of a product and is reported at 3 standard deviations below the average breaking strength. Safe Working Load (SWL) is the designated maximum working load for a piece of equipment or system based off a predetermined safety margin and the equipment’s minimum breaking strength. Agencies and/or users should establish their own SWL guidelines for individual components and for rigged systems. The specifications listed here are believed to be correct at time of printing.
