The Delta Plus I-675R 4-Point Mega Ratchet Replacement Suspension is engineered to deliver a secure, comfortable, and adjustable fit for Americana cap style and full brim hard hats. Featuring the advanced Secure-Fit™ Mega Ratchet system, this suspension allows precise size adjustments from head sizes 6.5 to 8 using an easy-turn knob—without removing the hard hat. Each adjustment locks firmly in place with 50 meshing teeth to prevent slippage, even in extreme weather or demanding jobsite conditions. The low-sitting, hinged ratchet and cushioned padding provide enhanced comfort and stability throughout the workday.
