ISC D5 Descender (12mm)


SKU: ISC-RP885 Category:


The D5 is a double-stop device with an auto-lock function, which is activated whenever the operator releases the handle; and a panic-brake function, which is not overly sensitive in normal use.
The D5 Descender also has a double-locking safety mechanism. In addition to the locking button, the side plates are designed such that the plates cannot be rotated open, whilst under load, due to the position of the Karabniner. The D5 is easy to attach/detach from the rope, without having to detach from the harness, therefore eliminating the risk of accidental dropping of the device.

The D5 features a progressive cam action, which offers precise control during low or high speeds. The cam is made from high grade, solid Descend Stainless Steel, for maximum durability, even in harsh environments, such as Geotech work.
A unique feature of the D5 Descender is that the handle rotates through 360 degrees and emits Panic audible ‘clicks’ as an indicator to the user of positive engagement of the mechanism.
