A jacket, sleeve or cover mainly serves to keep the core yarn strands together, it cannot be considered to be a protection sleeve. Depending on the material you choose, a cover could protect the core material from getting damaged in an early stage but will definitely NOT prevent the core to get damaged. Appropriate supplementary protections (on the bearing points, sharp objects etc.) are recommended as stated in the EN Standard 1492-2 for round slings. Extreema® jackets can also be used for the protection of your braided mooring or winching ropes and in the spliced eye constructions!

We offer four different options to cover the round sling.
