The NORMACLAMP® high-torque sign clamp is manufactured from components made entirely of stainless steel. The design of the worm gear housing on the strap allows for the installation of a wide variety of signs. The heavy-duty clamps are reusable. Their construction ensures that no sharp edges protrude during installation that could injure the installer. The recommended tightening torque for safe and reliable installation is 16 Nm, with a breaking torque of over 20 Nm.
