A 50M Kernmantle Lifeline Work at height often requires a rope system that provides enough vertical reach while remaining manageable during installation, access and retrieval. For façade maintenance, industrial structures, rescue work and tower applications, a 50 metre rope can offer a practical balance between working range and portability.

PN950(KRKD11)(121_TH)(ME) is a 50M Kernmantle Lifeline made from 11 mm polyamide kernmantle rope. This configuration includes a PN121 steel snap hook with a protected thimble at one end and a thimble-only termination at the opposite end. The rope also features a red and grey tracer for easier identification and inspection.

KARAM’s current 11 mm kernmantle anchorage-line range identifies PN950(KRKD11) as the 50 metre version. The manufacturer describes this rope family as polyamide kernmantle anchorage lines intended for temporary vertical or horizontal anchorage applications.

Nassguard supplies the 50M Kernmantle Lifeline across Qatar and Doha for construction, industrial maintenance, façade access, rescue applications, utilities and professional work-at-height requirements.

What is PN950 50M Kernmantle Lifeline?

PN950 is a Kernmantle Anchorage Line designed to provide a flexible rope connection for suitable height-safety and access systems. The rope uses a kernmantle construction, which combines an inner load-bearing core with an outer protective sheath. This structure helps the rope remain flexible while protecting the internal fibres from everyday surface abrasion. The KRKD11 version has an 11 mm diameter and uses polyamide material. KARAM lists this rope family in lengths from 10 m through 50 m, with PN950 corresponding to the 50 m configuration.

This particular PN950(KRKD11)(121_TH)(ME) version includes a PN121 steel snap hook at one end. The connector sits at a thimble-protected rope termination, helping limit direct metal-to-rope contact. The other end uses a thimble without an attached hook. This gives the user a protected rope eye that can be connected only through equipment approved for the intended system.

Technical Specifications

KARAM confirms that its 11 mm kernmantle anchorage line uses polyamide rope, and the PN950 reference represents the 50 m model.

The manufacturer lists the PN121 snap hook with alloy-steel construction, an 18 mm gate opening and a 23 kN minimum breaking strength.

Certifications, Standards and Compliance

• EN 1891:1998 – Low Stretch Kernmantle Ropes
• EN 362:2004 Class T – PN121 Connector
• IS 3521 (Part 5):2021 – PN121 Connector

The 50M Kernmantle Lifeline should be used only with equipment approved for the intended rope system.The same rope diameter does not automatically make a rope grab, descender, ascender or rescue device compatible. Workers should follow the equipment manufacturer’s instructions for rope diameter, rope type, connection method and system configuration.
