The Kosto CDK Series Self-Retracting Lifelines (SRLs) are engineered to deliver reliable fall protection with compact, lightweight performance. Featuring high-strength UHMWPE webbing, an integrated polyester tear-away energy absorber, and a durable thermoplastic housing, these SRLs are built to minimize free fall distance and reduce arresting forces in the event of a fall. Each unit includes a swivel aluminum carabiner for secure connection and smooth movement, ensuring confidence during work at height.

Key Features

Fast-acting braking system: Arrests falls quickly to minimize injury risk.
Energy absorption: Integrated polyester tear-away absorber reduces impact forces.
Durable webbing: 3/4" (19 mm) UHMWPE resists abrasion and wear.
Thermoplastic housing: Lightweight, compact, and impact-resistant.
360° swivel connection: Keeps unit properly oriented during use.
Multiple options: Available in 6 ft or 11 ft lengths, with large hook, small hook, or carabiner models.

Intended Use

These SRLs are designed for fall arrest in construction, maintenance, and industrial applications where lightweight, portable lifelines are required. The model variations ensure proper compatibility with different anchor points and harness configurations.

Roofing and construction crews working at height
Industrial maintenance teams on scaffolds and elevated platforms
Workers requiring compact SRLs for mobility in tight spaces
Environments needing CSA/ANSI/OSHA certified fall protection
