Sterling's 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 our extensive experience working with nylon/ polyester mixed material ropes. For the WorkPro, Sterling Rope 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. 11mm WorkPro has a minimum breaking strength of 8,092 lbs and rating of 36 kN Weight: 5.6 lbs / 100' Elongation at 300 lbs: 3.6% Sheath Slippage: 0.9% NFPA 2500 (1983), EN 1891:TypeA, ANSI Z133
