Your suspension is the backbone of your hard hat.
Hard hat suspensions are available in a ratchet or pinlock type. Pinlock suspensions feature pins and holes similar to a baseball cap and are more economical. They are available in 4, 6 and 8-point suspension types. Choose an 8-point suspension for ultimate head protection as it will absorb more impact than a 4-point suspension.
Ratchet suspensions feature a small knob that allows for quick and convenient sizing of the hard hat.
Hard hat suspensions should be replaced annually, or when they show cracks or tears, or loss of pliability.
