Product Description

What you get!!

D4 Descender - VISC RP880 RED

Work/Rescue Descender, an evolutionary development in the world of descenders! After hundreds of hours of trials, evaluation and feedback, eventually more than two years later we have officially launched the NEW D4 Work/Rescue Descender.
The D4 has a 240kg Working Load Limit which means it is suitable for two-man rescue on ropes of 10.5mm-11.5mm. It features a unique and innovative progressive cam action, which offers precise control at slow or fast speeds. The progressive cam works by way of one cam operating inside another cam. 
The D4 is a double-stop device with an auto-lock function which is activated whenever the operator lets go of the handle. 

RP891 RED Back-up (Fixed cord) 

The RED's cams have a positively locking spring, which means that the device is self-parking rather than self-tailing. This is important for Rope Access work techniques as they require the back-up device to be positioned so as to reduce fall factors to a minimum.

The RED makes use of 'Rotational Braking' which means the device rotates clockwise creating friction and resistance, which then results in very effective automatic braking in the event of a sudden pull on the cows-tail such as might occur during a main line failure.

Ideally used with the D4 descender in twin line applications

 Standards: EN12841
