WorkPro is a 12.5mm nylon and polyester static rope that is fully-certified and stronger than most other 12mm ropes. Ideal for Arborists, Window Washers and Rescue Teams. Compatible with popular hardware for climbing and descent systems, this rope is also easier to grip. Use as a climbing line for SRS and MRS. Strong and durable for Industrial rescue and safety applications as well as Tower Climbing, Window Cleaning, Stand-by Rescue Teams and Confined Space. Also compatible with most standard rescue devices and equipment and suitable as Standard Main and Belay System or Twin-Tensioned System. For the WorkPro, we 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 12 mm ropes of similar construction while retaining a small but important amount of elongation (2.2% @ 300 lbs.). Diameter 1/2" (12.5mm), MBS Rating: 10,116 lbs (45kN). Certified to ANSI Z133, EN 1891 Type A, NFPA 2500 (1983) and NFPA 1983 General Use. Made in the USA. Available in Lengths: 150', 200', 300', 600', 660' (46, 61, 92, 183, 200m) and in Red or Neon Green colors.
