The Low Profile configuration boasts a contoured locking head which is safer, more flexible and stronger than existing cable ties. SAFER because the stub is now deflected into a pocket at the rear of the head.  More FLEXIBLE because the flat lock section curves to the bundle contour and STRONGER because the Low Profile Tie uses an inline feature, eliminating the stress points of traditional cable ties.  Bundles down to 3/8" diameter and features pick-proof underside lock with all rounded edges
