Yates 799 ISC Red® Back-Up Device


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 ropes grabs). 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. The Red is tested and approved for “Two Person Rescue” Loads for Rope Access situations.
