Each of our Nitro headgear modules have 10 precise marks on each strap. Each mark is 2 mm apart. The total strap extension is 20 mm.
If a module is extended to the 5th mark (1/2 way extended), you know two facts:
1) the force level applied by the module from the charts below
2) the headgear strap can be extended 10 mm before the latch releases.
