ISC RED Back up Device w/ popper cord

The RED is a simple, yet highly effective back-up device.

The RED's non-aggressive Cams have a positively locking spring, which means that the device is self-parking (rather than self-tailing, like many Ropegrabs).  This self-parking function is important for Rope Access work techniques as they stipulate that the back-up device should be positioned so as to reduce fall factors to a minimum.

The RED makes use of 'Rotational Braking'- the more the device rotates clockwise, the greater the build up of friction, which provides the automatic braking in the event of a fall or sudden pull on the Cows-tail.  

To increase the effectiveness of the Rotational Brake in a panic situation (for example, a main-line failure), the RED can be fitted with a 'Popper' tow cord release clip*.  For further information on the Popper clip, please download the RED Back-up Device Datasheet.
