The 3M SecureFit Elevated Temperature H700T-Series Hard Hats with Pressure Diffusion Technology are designed to self-adjust to the wearer as the ratchet is tightened. This helps create a personalized fit and reduces the pressure on the forehead up to 30% compared to current 3M H-series hard hat suspensions. The smooth, easy turning ratchet suspension sits lows on the head to increase security and reduce pressure, helping to make the SecureFit H-Series a comfortable and stable hard hat option. The H-700T is designed specifically for elevated temperature applications ranging from metalworking and smelting to glass manufacturing as it withstands radiant heat loads up to 375°F.The 3M SecureFit H-Series Hard Hats provides 3M innovation in comfort while maintaining the traditional cap and full brim design that many prefer. If you wear a hard hat for a full shift, you want it to be comfortable and fit properly. 3M recognizes this and has responded by designing a suspension system that self-adjusts to the wearer as the ratchet is tightened. Chosen 9 times out of 10 over current conventional hard hats*, this suspension system flexes and self-adjusts to the size of the wearer’s head, reducing forehead pressure and increasing comfort for all-day wear.
