Salisbury by Honeywell 40 Cal Lift Front Hood offers a high level of arc flash protection. Hood with industrial bracket design creates a natural ventilation system that allows carbon dioxide and heat to escape as it rises from the body. Shield and chin guard provides an additional 45 deg of vertical view than other wood. It is lighter and more comfortable to wear. Reduction in the fabric allows for more natural head movement and eliminates the need for frequent hood adjustments due to shifts in the excess fabric. It allows for use of task lights to add much-needed convenience lighting in dark workplaces.
