Wire Rope Fall Arrest Block offers advanced protection for operatives working at height, incorporating durable steel wire and an intuitive braking mechanism. Designed to be used vertically, this fall arrest system engages automatically in the event of a sudden descent, helping to minimise impact on the user. With sizes ranging from 6m to 20m, it suits multiple site scenarios.

 

  • Durable polymer casing - High-strength shell that protects internal components and withstands tough site conditions.
  • Steel wire rope - Supplied in lengths up to 20m, 4.5mm thick, for vertical use only.
  • Braking mechanism - Instantly locks to arrest falls, reducing force transferred to the user.
  • Swivel snap hook with indicator - Allows safe attachment and visual confirmation of prior loading.
  • BS EN 360 compliant - Fully conforms to fall protection standards for UK industrial worksites.

 

This fall arrest system is engineered to serve demanding industries where worker safety at height is critical. Commonly used across construction, scaffolding, industrial maintenance, and roofing projects, it ensures fall protection performance where it matters most. Designed to stop a fall instantly, the steel wire and braking mechanism work in tandem to reduce impact force and prevent serious injury.

 

The unit supports personnel up to 140kg, making it a strong option for diverse operatives and site roles. With a high-strength polymer casing, it withstands knocks and rough handling without compromising internal safety features. The wire is available in lengths up to 20m, giving flexibility for various site layouts and anchor points.

 

For teams requiring reliable working at height safety equipment, this device delivers on all fronts. Its internal brake locks in milliseconds during a fall, and the swivel snap hook with fall indicator allows secure attachment and instant fault detection. Whether on a scaffold tower, platform, or edge application, the system protects workers from uncontrolled descents.

 

Ideal for safety managers and site leads responsible for PPE for working at height, the Wire Rope Fall Arrest Block provides assurance that users remain protected throughout their shift. With conformance to BS EN 360, you can be confident in both regulatory compliance and operational performance. Durable, effective, and simple to deploy, it’s a vital part of any fall arrest strategy.

 

HERMEQ stocks a wide range of equipment for Working at Height including Edge Protection Systems, Fall Arrest Systems, and Harnesses & Lanyards conforming to all required safety specifications and regulations.
