Petzl safety helmet Vertex white. The Vertex helmet, shown here in the colour white, ensures high wearing comfort thanks to its 6-point textile suspension and the Centerfit and Flipfit systems, which ensure excellent retention of the helmet on the head. Thanks to its chin strap with adjustable retention force, it is suitable for employees working at height as well as on the ground. The closed outer shell offers protection against electrical hazards, molten metal splashes and flames. The optimum integration of a Petzl headlamp, visor, standard hearing protection and numerous accessories makes it a modular helmet that fulfils the additional requirements of professional users. High wearing comfort: The 6-point textile suspension ensures an optimum fit. The centrefit adjustment system with its two side adjustment wheels ensures that the helmet sits centrally on the head. With the Flipfit system, the headband can be placed in the lower position to ensure that the helmet is optimally held in place. When the helmet is not in use and for transport, the system can be stowed in the helmet shell. Supplied with replaceable standard comfort padding. Head protection suitable for working at height and on the ground: The dual chin strap allows the user to change the retention force of the chin strap to adapt the helmet to different work situations: Working at height (EN 12492) and working on the ground (EN 397). The clip has two positions for two different uses: high retention force to reduce the risk of the helmet being torn off the head in the event of a fall, and low retention force to reduce the risk of strangulation if the helmet gets caught when working on the ground. Shock absorption through deformation of the outer shell. Protection against electrical hazards, molten metal splashes and flames thanks to the closed outer shell.
