SupraPlus and "Joker" adapter safety hook: Always a suitable connection! From 1 to 6t rated capacity. The Joker hook is ideally coordinated with the SupraPlus roundslings. Special laterally raised forged lobes protect the textile slings from abrasion and for a textile channel for perfect guiding. This avoids impermissible crushing of the roundslings and resulting rated capacity reductions.
