The ISC Chest Ascender is compact & lightweight and has been designed for use on a full body harness. Although compact, the device has been ergonomically designed for ease of use, allowing the user to easily add/remove the rope as required (even whilst wearing gloves). The RP229 Chest Ascender body is made from Aluminium, fitted with a Stainless Steel cam and cam-latch, for durability. The spring-loaded latch allows easy one-handed operation whilst attaching/detaching the device to/from the rope. The Chest Ascender rivets are also made from Stainless Steel, for improved corrosion resistance and durability. The ISC Chest Ascender has a positive grip at low load- even on wet, greasy and oily ropes.
