Please contact us for urgent orders.

Multi functional Prism descender 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. User can switch from one configuration to the other while device is loaded:

Normal Friction –

  • Will brake if the handle is released or if it is squeezed fully. Prism does not require additional friction from a second karabiner to hold higher loads.

Reduced Friction – used for:

  • Ascending, paying 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,

The heightec Prism provides a hands free locking function and can be changed from lift to lower whilst under load. It is a core component in the Advanced Lifting and Lowering Kit.
