P-SLSR OSHA approved cap-style hard hat with an 8-point ratchet suspension. Must be ordered in even cases of 16 hats. OSHA-approved hard hat meets or exceeds the requirements for a Type 1 helmet (Top impact) as required by ANSI Z89.1-2009, Class C, G & E. Fits head size 6 1/2 to 8. Very similar to the Fibre-Metal FM-1 E1RW01A000.
