ISC D4 Work/Rescue Descender features a unique and innovative cam action, which offers precise control at slow or fast speeds. Rope capacity is 10.5 to 11.5mm (7/16in) in diameter.
The D4 uses a camming action that holds/stops the users weight on the rope. Actuating the lever allows controlled lowering and descent and the built in anti-panic safety prevents uncontrolled or over -speed descent. The anti-panic feature was designed with input from professional users and allows precise controlled descent without some of the side-effects seen in similar devices.
The D4 can also be used in countless mechanical advantage and progress capture applications.
