How it works

It brakes like a car.

  1. 01

    Braking

    Friction pads against internal surfaces, the way a car slows.

  2. 02

    Speed

    One constant rate from 30 to 125 kg. No adjustment.

  3. 03

    Descent

    Smooth, stable, jerk-free. No free fall.

  4. 04

    Power

    None. No motor, no battery, no electronics.

Questions

Before you decide.

The questions we hear most, answered plainly.

Something else? Ask on WhatsApp
01How often does it need inspection?

Inspect it once every 4 weeks, and before any use.

02Can a child use it?

The device is speed-regulated from 30 to 125 kg — a 30 kg child descends at the same controlled speed as a 125 kg adult, automatically.

03What if the power is out?

It needs no power at all. No batteries, no electronics — a fully mechanical friction-braking system, unaffected by an outage.

04How long does installation take?

It's a quick installation, done by our team at your location.

05Can it be reused?

Not after an emergency descent — it must then be taken out of service. Service life is 3 years.
