Sterling WorkPro 11 mm
Semi-static work rope developed for professional rope work in demanding conditions.
Sterling WorkPro 11 mm combines a nylon core with a polyester sheath. The construction balances the stretch in the core and sheath, so that they share the load evenly. This provides high breaking strength while the rope retains a controlled amount of stretch.
WorkPro was developed through practical testing and feedback from professionals in access techniques. The rope is produced in the USA and is available here in two color and length combinations.
