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.
