MSA Safety Self-Retracting Lifeline, 339.000mm Length, 5mm Diameter - 63310-00AEU

This self-retracting lifeline provides controlled fall arrest for personnel working at height in industrial settings. It is intended for use where a compact, automatically retracting lifeline is required to limit fall distance and reduce free-fall forces. The unit combines corrosion-resistant components and a robust case material to suit routine use in electrical, mechanical and automation environments.

Features and Benefits:

• 5mm line diameter delivers Compact storage and dependable retraction
• 339mm line length allows restrained movement during tasks
• 140 kg rated capacity supports a single-user fall arrest scenario
• Stainless steel drum module resists wear and corrosion
• Forged zinc-plated snap hook with load indicator simplifies inspections

Applications

• Suitable for maintenance on electrical cabinets and panels
• Ideal for technicians working on production-line machinery
• Used for access tasks on mechanical assemblies and gantries
• Can be used for installation work in automation enclosures

What materials reduce corrosion risk in mixed environments?

Critical load-bearing components use stainless steel and galvanised elements while the snap hook is forged zinc-plated to limit degradation where moisture or contaminants occur.

How does the device indicate impact or loading events?

A load indicator integrated into the snap hook provides a visible sign when the connector has been subjected to arresting forces.

What is the construction of the housing and key internal parts?

The outer Shell is a polycarbonate/ABS blend with a stainless steel chassis and an aluminium threaded plate supporting the drum and retraction spring assembly.
