Petzl DUAL Extended

Petzl DUAL Extended

Petzl DUAL Extended



Not all heads are created equal in terms of shape. Combine a longer shaped head with bulky ear protection and the standard Petzl Vertex or Petzl Strato chinstrap might interfere with the cushion on the muff, allowing sound to enter the ear. The Dual Chinstrap Extended is a slightly longer version of the original. The extra length keeps the chinstrap crossover out of the way of the earmuff. The Dual Chinstrap also enables modification of the chinstrap strength to adapt the helmet to different environments: work at height or on the ground.

  • This chinstrap allows the chinstrap of 2019 VERTEX and STRATO helmets to be changed or replaced.
  • Allows the worker to modify chinstrap strength to adapt the helmet to different environments: work at height (EN 12492) or on the ground (EN 397). The clip has two positions, for these two uses: high strength, limiting the risk of losing the helmet during a fall, and low strength, limiting the risk of strangulation if the helmet is snagged while the user is on the ground.
  • Equipped with lateral separator to adjust strap length.
  • Relatively easy to install.
  • Original equipment part from Petzl.
