Abstract: A cable tie structure for bundling cables may include a preformed strap body having a convex inner surface, the preformed strap body comprising a receiver end and a toothed end, the toothed end having a plurality of teeth extending from at least a portion of the inner surface and designed to engage with the receiver end. The locking head may include an L-shaped overhand retainer arm formed of a side wall extending substantially perpendicularly from the strap body; an upper wall extending substantially perpendicularly from the side wall at an end of the side wall distal from the strap body such that the upper wall is substantially parallel to the strap body; and an open side opposite the side wall. A clip arm may extend at an angle from the strap body toward the upper wall. The clip arm may include clip arm teeth and a beveled outer edge.
