STREAM CLIMBING STEPS Panther  consists of four main parts. 
  • Hook,
  • spikes,
  • shell
  • and clamping elements.

The main supporting element is a hook , which is made of a special aluminum alloy. After several heat treatments, it has parameters that guarantee maximum safety for the user. These parameters were tested in the laboratory of the Faculty of Mechanical Engineering of the Czech Technical University in Prague and the result was the finding that the hook can withstand 650 kg without significant deformation. At higher loads, irreversible deformation occurred, but not cracking.

The second supporting element are three types of spikes.All are cast from alloy steel (Cr, Ni, Mo). After thread cutting and subsequent heat treatment, when the spikes are tempered to a value of 1000-1200 MPa, they are screwed to the hook with a pair of M8 screws. These screws are tightened to a value of 25N / m and a layer of glue is applied to them, which prevents their spontaneous loosening. The spikes are shaped so as to allow the underlining of a leather or synthetic strap, which ensures the stability of the foot in the area of ​​the ankle. Due to the perpendicular to the base, the grinding angle is 30 °.
The spikes were also tested in the above-mentioned laboratory and up to 650 kg there is no significant deformation or breakage. At higher values ​​up to 1000 kg, the tip of the spike is permanently deformed, but does not break.

The third element is the shell.It is made of several layers of glass fabric and reinforced with a strip of carbon fabric. The openings in it allow the movement of this support with regard to the needs of the user. The shell is attached to the hook with a pair of M6 screws. The calf support is attached to this shell with the help of velcro. This is shaped longitudinally to provide maximum comfort to the user.

The leg is attached to the hook with either textile stripes with velcro or a leather strap .
