Rapid Rapel Replacement rope with rope protection

Replacement 4mm Technora Fire-Resistant Rope for the 4.1 Tactical decent system. 

The rope is made from 100% Technora, a top-tier para-aramid material known for:

• Superior strength and flexibility compared to Kevlar

• Minimal strength loss even after repeated use

• Resistance to water, steam, and chemicals

• High melting point of 500°C

The rope is replaceable on training and operational devices that are revalidated by an authorized entity.

Rope Specifications

• Diameter: 4 mm

• Weight: 13.6 g/m

• Elongation: 0.4%

• Minimum strength: 15.3 kN

• Average strength: 16.7 kN

Certification

The VVUU, a.s. has carried out assessments on the system in accordance with EN 341:2012 / EN 365:2005. It is classified as Type/Class 2/D single use.

However, military, law enforcement, and experts may have authorization to depart from these regulations and utilize the device repeatedly. Organizations or units approved by the manufacturer can revalidate the device for reuse and maintain certification.

The system was tested with a 175 kg load for 50 m descents under dry, wet, cold, and very cold conditions.

In the event of an unexpected freefall, the brake is designed to slide down the rope to reduce force. During certification, a 140 kg test mass was dropped from 60 cm, and the maximum peak force recorded was 4.1 kN.

Non-Certified Version for Multiple Descents

The 4.1-Tactical device is engineered to support multiple descents. However, due to certification limitations and the absence of specific regulatory standards for multi-use, it cannot be marketed as a multi-use device under EN certification.

To address this, the manufacturer provides an uncertified edition designed for advanced applications, without restrictions on the number of descents.

Specialized training is recommended for personnel using the device in multiple-descent scenarios. As with all safety equipment, it remains the operator’s responsibility to carefully assess the integrity of the device before each use and determine when it requires replacement.
