100M kernmantle lifeline large structures and extended vertical work areas often require much more rope coverage than a standard 20 m or 50 m lifeline can provide. For towers, façades, industrial plants and infrastructure projects, a longer rope can reduce the need to reposition the anchorage line repeatedly.

PN9100(KRKD11)(121_TH)(ME) is a 100M Kernmantle Lifeline built around an 11 mm kernmantle rope with a red and grey tracer. According to the supplied product configuration, the rope measures 100 metres and includes a PN121 steel snap hook with thimble at one end, while the opposite end has a reinforced thimble only.

KARAM’s current KRKD11 anchorage-line family confirms the use of 11 mm polyamide kernmantle rope for this rope series. The manufacturer also states that its textile anchorage lines are intended for temporary vertical and horizontal anchorage applications when used with compatible equipment.

Nassguard supplies the 100M Kernmantle Lifeline across Qatar and Doha for professional work-at-height, industrial maintenance, façade access, utilities, construction and selected rescue applications.

What is PN9100 100M Kernmantle Lifeline?

PN9100(KRKD11)(121_TH)(ME) is a long Kernmantle Anchorage Line designed for applications where workers need extended rope coverage. The rope uses a kernmantle structure. In this construction, the inner core carries the main load while an outer sheath protects the core from routine surface wear. This combination gives the rope a practical balance of flexibility and protection.

The KRKD11 rope family uses 11 mm polyamide kernmantle rope. KARAM identifies this rope type as part of its textile anchorage-line range for work-at-height applications. For this specific PN9100 configuration, the rope length is 100 metres. That extra reach makes the product suitable for taller structures and longer access areas where shorter lifelines would require frequent repositioning.

One side includes a PN121 steel snap hook fitted through a protected thimble. The opposite side terminates in a thimble only, allowing the rope end to connect through a suitable approved anchorage arrangement.

Technical Specifications

KARAM confirms that the KRKD11 anchorage-line family uses 11 mm polyamide kernmantle rope.

For the PN121 connector, KARAM lists an alloy-steel body, 18 mm gate opening and 23 kN minimum breaking strength. The hook also uses an auto-closing and auto-locking spring mechanism.

Certifications, Standards and Compliance

• EN 362:2004 Class T – PN121 Connector
• IS 3521 (Part 5):2021 – PN121 Connector

System Certification and Compatibility

KARAM states that its textile anchorage lines are certified as a system only when used with specified KARAM rope-grab fall arresters. Therefore, users should not assume that every rope grab designed for an 11 mm rope automatically forms a certified system with PN9100.

This makes system compatibility particularly important. The rope, fall arrester, connector, harness, anchorage point and any additional components must match the manufacturer’s approved configuration.

Conclusion

PN9100(KRKD11)(121_TH)(ME) provides extended rope coverage for work environments where a 50 metre line cannot reach the full working area. Its 100 metre length makes it suitable for tall buildings, towers, industrial structures, utility installations and other projects with considerable vertical distance. The 11 mm polyamide kernmantle construction combines a protected inner core with an outer sheath, giving the rope practical flexibility while helping protect the load-bearing fibres from surface wear. KARAM confirms this 11 mm polyamide construction for the KRKD11 rope family.

At one end, the PN121 steel snap hook provides an auto-closing and auto-locking connection. Its 18 mm gate opening and 23 kN minimum breaking strength support professional height-safety applications. The opposite thimble-only end provides a reinforced termination that can connect through equipment selected for the specific system. For construction, high-rise maintenance, towers, utilities, industrial facilities and suitable rescue applications, the 100M Kernmantle Lifeline offers extended working coverage in a manageable kernmantle rope format.
