Donahys Armor-Prus is one the most popular 'heat-resistant' friction cords available on the market. A bit over a year ago, the powers that be started making noises about potential safety concerns regarding the splice being employed to make eye-to-eye Armor-Prus friction cords (commonly used in the ubiquitous 'Hitch climber' set-up).
The debate centered around the fact that some climbers were splicing Class II double braid Armor-Prus (Spectra/Kevlar core/Blended Technora/Polyester Sheath)
cord with Class I (100% Polyester) splicing instructions.
While the Treetools/DB Tree tests proved a point (to a degree), there was still a lingering doubt about the use of a Class I splice on a Class II cord? You will see the trend reflected under the heading 'Top Product Migration' for 2010.
The ideal answer appeared to be the production of a friction cord that utilized the tried and proven Armor-Prus heat-resistant sheath over a 100% polyester core to accommodate the use of the Class I splice.
Rumor has it, such a friction cord is currently being developed. If the murmurings are true, it could spell REAL BENEFITS for tree climbers! What this space!
