The Flagship Model

RST-24 Friction Braking

Traditional magnetic brakes fade. Hand braking fails. The RST-24 uses adjustable friction pads and patented geometry to mechanically regulate deceleration, providing a consistent, smooth stop every single time.

Dual Brakes

Redundant independent braking plates ensure safety even if one side is compromised.

Slope Calibration

Easily adjust the braking force for any zipline slope using our multi-slot carabiner system.

Zipline Spring Stopper

Feel Safer

Barrel SpringZipline Spring Stopper

Our patented RST Barrel Spring zipline stoppers are the ultimate in zipline safety and fun. Our durable spring zip line brakes ensure safety and fun for kids and adults, lasting up to 200,000 uses or 4 years. Plus, they don't need to be sent for inspection every year like other, costlier options.

No Guesswork

Simple installation, then rest easy knowing your zipline system stops riders safely. Just add one spring per 1mph for zipliners up to 250lbs. For up to 350lb zipliners, use 1.5 times springs per 1mph arrival speed. (8mph = 12 springs)

PATENTED SPRINGS

Our patented Barrel Spring zipline stoppers will safely slow riders and ensure ziplining fun for years-As they have done for 24 years at resort ziplines with zero accidents. Fits up to 1/2-inch diameter ziplines and cables.

The Weight Equalization Advantage

Why ZipSafe out-performs magnetic braking every time.

Physics, Not Magic

Our trolley adjusts friction based on force. A 35 lb child and a 275 lb adult will stop in the same location.

Rider Independent

The braking process is completely passive. No hand braking required, eliminating human error and panic reactions from the safety equation.

Field Serviceable

Designed by operators, for operators. Change brake pads in minutes without removing the trolley from the cable.

High Throughput

Reset in seconds, not minutes. No waiting for magnetic fields to reset or electronics to reboot.

Troy Richardson, Founder

The "Accident-Free" Standard

"I've served as an expert witness in too many zipline injury cases. I founded ZipSafe to solve the problem at the source: The Trolley. We don't just mitigate impact; we eliminate it."

With over 20 years of field operation and patented innovations like the Barrel Spring Emergency Arrest Device, our mission is simple: Zero accidents.
