The Kosto CDKL Series Leading Edge Self-Retracting Lifelines (SRLs) are engineered for tough fall arrest applications where contact with sharp edges is a risk, such as rooftops and structural steel work. Built with galvanized steel cable, a polyester tear-away energy absorber, and a rugged thermoplastic housing, these SRLs combine durability with reliable performance. Each unit features a swivel aluminum carabiner with fall indicator, ensuring secure connections and improved safety awareness.

The series is available in five lengths to match specific jobsite needs:

CDKL08: 8 ft (2.4 m) compact SRL for confined or close-range tasks.
CDKL22: 20 ft (6 m) SRL offering balanced reach for general construction.
CDKL32: 30 ft (9 m) SRL suited for larger-scale roofing and steelwork.
CDKL52: 50 ft (15 m) SRL providing extended mobility for high structures.
CDKL62: 66 ft (20 m) SRL for maximum reach in industrial and tall-building environments.

Key Features

Leading edge protection: Engineered to perform safely in sharp edge applications.
Energy absorber: Polyester tear-away design lowers arresting forces.
Durable construction: Galvanized steel cable with thermoplastic housing.
Fall indicator carabiner: Alerts users to prior fall events for added safety.
360° swivel connection: Keeps the unit properly aligned during use.
