The Kosto CLKY series double energy-absorbing lanyards are designed to deliver continuous fall protection while allowing workers to remain 100% tied-off when moving between anchor points. Built with durable polyester webbing and an integrated energy absorber, these lanyards help reduce arrest forces by gradually dissipating energy during a fall. This product family includes multiple configurations to suit different jobsite needs: CLKY42 with three small double-locking hooks for standard anchor points, and CLKY40 / CLKY60 with one small hook for harness connection and two large hooks for oversized structural anchors. Engineered for high-risk environments, these lanyards provide reliable performance, flexibility, and compliance in fall arrest systems.

Key Features

100% tie-off safety design: Double-leg configuration allows continuous attachment when transitioning between anchor points.
Integrated energy absorber: Reduces fall arrest forces by progressively absorbing kinetic energy during a fall event.
Multiple hook configurations: Available with three small hooks (CLKY42) or combination of small + large hooks (CLKY40 / CLKY60) for versatile anchorage compatibility.
Durable polyester construction: High-strength webbing ensures resistance and reliability in harsh work environments.
Double-locking steel hooks: Secure connection with galvanized steel hardware for enhanced safety and durability.
Flexible anchorage options: Large hook openings (2.2") available for structural steel and oversized anchor points.
Label protection system: Built-in label protector helps maintain traceability and product identification over time.
Pack-style energy absorber: Compact and efficient design for reliable deployment and reduced bulk.

Intended Use

These double energy-absorbing lanyards are designed for fall arrest systems where workers must remain continuously connected while working at height. They are particularly effective in applications requiring movement between multiple anchor points and compatibility with various anchorage sizes.

Construction workers operating at height (steel erection, roofing, framing)
Maintenance crews working on elevated structures or platforms
Industrial workers in manufacturing or processing facilities
Utility and energy sector technicians (power lines, infrastructure)
Confined space or structural access work requiring secure positioning
Situations requiring compliance with CSA and OSHA fall protection standards
Tasks involving frequent repositioning or movement between anchorage points
