01 Overview

Heightec Prism Descender is multi functional and specifically designed for rope access. High capacity rope descender can be used for abseiling, ascending, lowering, hauling and rescue.

Multiple threading configurations provide different levels of friction. The user can switch from one configuration to another while device is loaded.

Normal Friction - will brake if the handle is released or if it is squeezed fully. The Prism does not require additional friction from a second carabiner to hold higher loads.

Reduced Friction - used for ascending, playing rope in and out, or under partial load, such as when moving across a horizontal surface towards an edge prior to abseiling.

Meets selection criteria of IRATA international code of practice. March 2013,

Locks id handle is released or squeezed too hard. Suitable for 2 person loads.

Patented duo brake mechanism increases friction under heavy loading and reduces rate at which friction is released

Inspection and cleaning is simple as all component parts of the device are visible and accessible

Stainless steel friction surfaces for reduced wear and consistent performance

Can be used as a releasable anchor in a rig for rescue systems.

The Prism provides a hands free locking and can be changed from lift to lower whilst under load.
