NORMA CLAMP® COBRA products are bolt-free, one-piece hose clips. Their low overall height enables precise installation in even the tightest of spaces. NORMACLAMP® COBRA clamps are quick and easy to install. They have a self adjusting diameter which compensates for tolerances at the outer diameter of the hose. They are colour coded to provide a rapid way of visually distinguishing between nominal diameters and they have a single lock-in point which provides an installation indicator for easy checking.
