The Skullgard hard hats use a dial to denote when the hard hats were produced. The dial is separated into 4 quadrants and each section has a year stamped into that area. Each year is further separated into 4 small squares showing the quarter of that year. The way to read the manufacturing date is to check and see where the little dots stop on the dial.
So, if the dots stop in square 4 of the year 2024, that would show the hat was produced in the 4th quarter of 2024. Similarly, if the dots are all full in 2024 and then there is 1 dot in 2025 that would show it was made in 1st quarter of 2025. The hats are typically good for 5 years of shelf life and or two years of service.
