The handle rotates all the way around (360 degrees). You can just keep spinning it round and round.
Itís made of thicker aluminum than the Petzl IíD, so it is more durable.
The handle and several other parts will be replaceable.
The anti-panic is somewhere between an Petzl IíD and a Rig in terms of sensitivity.
Itís like a Rig in that it doesnít have a dummy proof mechanism to keep you from loading it backwards.
At this time, ISC is planning to release the D4 descent control device for 11mm, with a 12.5mm coming shortly after.
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), this is fitted with a 'Popper' tow cord release clip*.
