Sterling Ropes has long been trusted as a manufacturer of top-quality climbing, access, and rescue lines, and now with Atlas they have delivered their first tree-rigging line.
Sterling Atlas is a double-braid tree rigging rope with a Polyester cover over a Nylon core. The Nylon core provides not only great strength but increased elasticity. This extra stretch helps to mitigate loads created when catching wood, and reduce peak forces.
Sterling Atlas has a great hand and a firm, round cross-section which has been designed to work excellently with bollards on the GRCS or Port-a-Wrap.
Atlas is currently only available in 9/16" diameter, making it perfect for most everyday rigging work. A factory-spliced eye is available by special order.

The American National Standards Institute (ANSI) has released the ANSI Z133 safety requirements which apply to arboriculutral operations. Components of a rigging system must be used within their Working Load Limits.
This product is ANSI compliant when used within the manufacturer Working Load Limits.
A green log weight chart will aid in determining the loads in tree rigging.
The full ANSI Z133 safety requirements are available on our tree care standards page.
