    How do I set the chinstrap strength?
    The chinstrap strength should be set in accordance with the risk assessment carried out for the planned helmet use.

    - Risk of helmet coming off in a fall – Strong strength >50kg or 490N

    - Risk of strangulation – Weak strength <25kg or 245N

    One of the parameters in the helmet EN Standard’s relates to chinstrap strength:

    - EN 397 – requires a chinstrap strength (if fitted) <25kg or 245N

    - EN 12492 – requires a chinstrap strength >50kg or 490N

    Use a small flat-head screwdriver to turn the chinstrap clip to the desired setting. 

    How do I adjust the fit of my Petzl Vertex?
    Push in both headband adjustment wheels and turn them in the same direction until the desired fit is achieved.

    Move the webbing through the chinstrap positioning buckles to move the chinstrap forward or backwards. 

    Carefully unclip the front headband and move it up or down to achieve the desired fit.   

    Move the rear headband so that the webbing is tight.

    Test the fit by pushing up on the front brim. There should be limited movement.


    How do I remove / install the chinstrap?
    Use a flat-head screwdriver to carefully depress and remove the chinstrap retaining clips on all four ‘corners’.
