The Breeze Constant-Torque® Heavy Duty (HKF) is a breakthrough in fastening technology. The special disc spring mechanism allows the constant-torque clamp to automatically expand or contract in diameter depending on the influences of operating or ambient temperatures. The unique design eliminates leaks caused by cold flow. With its 16 mm band and 10 disc springs, this clamp is the ideal solution for heavy-duty applications with temperature fluctuations.
