Open head cable ties designed for temporary locking before being fully tightened. The temporary lock enables initial and final sorting of cable tangles. Internal grooves ensure retention of cable tangles in the intended place. Thanks to being made of Polyamide 6.6, they are perfectly suited for both indoor and outdoor use at temperatures from -40°C to 85°C. They are characterized by good resistance to oils, fats, alkalis, petroleum products and chloride solvents.
