Sterling WorkPro is a new style of rope that sits somewhere in between a typical Arborist Double Braid rope and a Static Access line.  This makes it ideal for SRT Work Positioning for the modern Arborist on devices like the Rope Wrench, Rope Runner, or Unicender.

Sterling Ropes newest static rope is the direct result of a rigorous in-use testing and evaluation process with rope access professionals working in variable and harsh conditions. The final design incorporates their feedback and benefits from their extensive experience working with nylon/ polyester mixed material ropes.

For the WorkPro, they developed an entirely new approach to rope construction—one that makes for balanced elongation in the core and sheath so they share the load evenly. This makes the WorkPro stronger than other 11 mm ropes of similar construction while retaining a small but important amount of elongation.
