The Kosto CLKY40 and CLKY60 double-leg energy-absorbing lanyards deliver reliable fall protection and continuous tie-off capability. Featuring a pack-style tear-away absorber, they are designed to dissipate energy during a fall, reducing arresting forces for worker safety. Built from durable 100% polyester webbing, these lanyards integrate a small double-action snap hook for secure dorsal D-ring attachment, and two large snap hooks to accommodate oversized anchorage points. Available in 4 ft (1.2 m) and 6 ft (1.8 m) lengths, they provide flexibility and strength for use in high-risk industrial environments.
