Fall arrest device MAS SK 12 with 1.4 m rope, 12 mm rope diameter

The MAS SK 12 fall arrest device with 1.4 m rope and 12 mm rope diameter is a compact, single-user energy-absorbing assembly designed to arrest a fall and reduce impact forces on the body during work at height. The unit combines a controlled deceleration mechanism with a fixed-length rope to form a secure connection between the worker and a suitable anchor point. It is intended for use where a short lanyard and reliable energy absorption are required to limit fall distance and reduce loading on the harness and attachment points.

Advantages

The device integrates an energy-absorbing element that deploys during a fall to limit peak forces transmitted to the user. Its 1.4 m rope length provides a compact working reach while minimizing free-fall distance. A 12 mm rope diameter offers a balance between flexibility and durability, ensuring easy handling and long service life under normal use conditions. The compact design facilitates attachment to standard harnesses and anchor points and supports straightforward inspection and maintenance routines.

Suitable for

• Construction and scaffolding work where short connection lengths are required
• Maintenance tasks on platforms, rooftops, and towers with nearby anchor points
• Industrial environments with confined access where controlled deceleration is necessary
• Rescue and evacuation scenarios requiring reduced fall clearance

Key specifications

• Rope length: 1.4 m
• Rope diameter: 12 mm
• Function: Fall arrest with energy absorption
• User capacity: Single user (designed for individual connection)
• Attachment: Designed for connection between harness attachment point and anchor

How to use

Attach the device to the designated dorsal or sternal attachment point of a compatible safety harness using the specified connector. Secure the opposite end to a certified anchor point capable of withstanding fall arrest forces. Before each use, visually inspect the rope, energy absorber housing and connectors for wear, damage, or contamination. During a work session, keep the rope clear of sharp edges and moving parts. In the event of a fall arrest activation, remove the device from service and replace or have it serviced according to the manufacturer’s procedures.

Usage recommendations

Use the MAS SK 12 fall arrest device only as part of a complete fall protection system that includes an appropriate harness, certified anchors, and trained personnel. Ensure compatibility of connectors and anchor types, observe local regulations and standards for work at height, and follow routine inspection intervals. Do not use the device if the rope or housing shows signs of damage, and replace the unit after any fall arrest event or according to the manufacturer’s service life guidance.
