Alko Plus safety helmets act as the first line of defence against head injuries. These safety helmets are crucial to ensure workplace security. Safety helmets should be wielded during constructional, industrial and mining activities. Alko Plus APS 131 is a reliable safety helmet modelled under Alko Plus safety helmets that are designed with a specially formulated polymer to enhance strength. It has increased vertical clearance, along with cooling vents at the crown to increase airflow. Alko Plus APS 131 can, therefore, be used in hot weather conditions. This safety helmet comes with a ratchet adjustment which can be set to the correct head size by turning the hand-wheel. The adjustment position will be locked when the hand-wheel is released.
