The Kosto CDK350 3-Way Self-Retracting Lifeline is engineered for high-risk environments where fall protection, rescue, and retrieval must be integrated into one reliable system. Featuring a 66-foot galvanized steel cable, this SRL-R provides controlled fall arrest while enabling quick transition to winch mode for emergency recovery operations. The aluminum housing protects internal components without adding unnecessary weight, while the ergonomic recovery handle allows efficient lifting or lowering during confined space interventions. Designed for compatibility with tripod systems such as CTK012, this device delivers critical safety performance for workers operating at height or in confined spaces.

Key Features

3-way rescue functionality: Combines fall arrest, retrieval, and winch capabilities in a single device for maximum versatility.
Galvanized steel lifeline: 66 ft (20 m) durable cable designed for strength and reliability in demanding environments.
Ergonomic recovery system: Integrated handle allows quick activation of winch mode for efficient rescue operations.
Swivel indicating carabiner: Double-action aluminum connector with rotation helps prevent twisting and accidental disengagement.
Lightweight aluminum housing: Protects internal components while maintaining portability and ease of handling.
360° rotating connection point: Helps maintain optimal orientation during use and reduces lifeline stress.
Tripod compatibility: Designed to mount on tripod systems using a dedicated bracket (CTK910), ideal for confined space setups.

Intended Use

This 3-way SRL-R is designed for applications requiring both fall protection and emergency retrieval, particularly in confined space environments or vertical work zones. It supports safe worker mobility while ensuring rapid rescue capability when needed.

Confined space entry and rescue teams
Industrial maintenance and shutdown crews
Oil & gas, utilities, and municipal workers
Construction workers operating at height
Tank, manhole, and shaft access operations
Situations requiring integration with tripods or anchorage systems
