Singing Rock SIR is a robust multipurpose device developed for professional use in industrial rope access and rescue systems. The manufacturer states that its functionality covers use as a rope descender, abseiling device, belay and fall-arrest device, and work positioning device, making it a highly versatile solution for work at height.
The device works through a cam-based mechanism: pulling on the working end of the rope engages the cam and jams the rope, while pulling the lever gradually releases the rope. If the lever is pulled to its terminal position, the antipanic function is triggered and blocks the rope again. To adjust rope length without load, the mechanism can be released with one hand by pressing the pivoting cam directly with the thumb.
The manufacturer also highlights easy and intuitive rope installation and a design that allows easy inspection. The device can be additionally secured against dropping with a reep cord tied into the eyelet. It is a practical choice for rope access technicians, rescuers, and professionals who need a dependable descent and work positioning device.
