The TRUBLUE™ SafeLine is the ultimate controlled descent device, protecting dropped people and objects while allowing dynamic movement without nuisance lockups.
Originally designed for climbing safety, 60,000+ TRUBLUEs are in use around the world, providing millions of controlled descent every day.
SafeLine’s self-regulating magnetic braking system is the result of years of research, development, and testing. TRUBLUEs are engineered to meet the strictest safety standards, including extensive testing by one of the leading certification bodies in the world.
The TRUBLUE is available in two webbing lengths:

It’s better than the rest because there’s nothing else like it. TRUBLUE SafeLine uses patented magnetic braking technology, also found in high-speed trains. This provides controlled descents allowing for dynamic movement without nuisance lockups, and friction-free, reliable braking that eliminates brake pads and reduces wear and maintenance.
Each device undergoes extensive third-party testing by an ISO 17025 accredited lab, ensuring top-tier safety and performance. This results in an extended device lifespan and higher cycle capacity, making TRUBLUE the safest, most durable controlled descent device on the market.
TRUBLUE SafeLines are life-safety devices, and annual service inspections are crucial to maintaining safety standards and ensuring your device warranty remains valid. Lives are quite literally on the line!
Each service includes a comprehensive 62-point inspection, repairs or replacements of worn parts (including webbing), cleaning, and testing across a full range of weights to ensure optimal performance.
TRUBLUE SafeLines require service inspections 15 months after the manufacturing date and every 12 months thereafter to ensure a high standard of performance and safety.
We offer a SafeLine Service Subscription program, which provides a quick swap for a recertified fleet device with zero downtime, as well as other benefits.
TRUBLUE SafeLine with 12.5m (41ft) webbing:
- Maximum mounting height of 12.5 m (41 ft)
- Minimum mounting height of 4.5 m (14.8 ft)
TRUBLUE SafeLine with 20m (65.6ft) webbing:
- Maximum mounting height of 20 m (65.6ft)
- Minimum mounting height of 12 m (39.4 ft)
It is important to note that the maximum and minimum mounting height limits listed for all SafeLine models are requirements, not recommendations. To ensure safe operation, devices must be mounted within the specified mounting height range.
For more information, please refer to our Mounting Heights Specifications whitepaper.
The mounting height for all SafeLine models is measured from the nozzle of the device to the ground.
