MASK FRONT ANGLE TEST GAUGE
A tool for armourers for testing the angle at the front of a mask.
DESCRIPTION
Masks must have an angle of less than 130 degrees. Masks that have a flatter profile on the front are dangerous as blades can catch on the front of the mask mesh instead of being deflected to the sides. This is a handy device for measuring the front angle to ensure the mask is legal.
面罩必须具有小于130°的角。
是一个手持测量前角以保证面罩是合体的装置。
